Most of our readers have probably used a DVR (Digital Video Recorder) device at some point in time. TiVo was the first such device to gain mainstream recognition, but in reality, PC owners have been able to do most of what TiVo offered for a long time. ATI's All-In-Wonder line has had TV-In capability since the days of the old ATI Expert line with Rage graphics chips. Of course, the ability to do something like watch or record TV on a PC is not the same as the ability to do that well, and thankfully, we've made some serious progress in that area over the past decade. Our last TV tuner card roundup is almost six months old, and while much of the information is still current, we do have some new cards some might be considering.

Today, we have a trio of TV Tuners for review, and while they have some similarities, they're also quite different in features, software, and performance. Two of the cards are - as far as I'm aware - the only HDTV tuners currently available for Windows that will handle QAM decoding. The cards are the MyHD MDP-130 and the DVICO Fusion5 Gold. (Older DVICO and MyHD cards may have handled this as well, to varying degrees.) The third card marks one of the first truly interesting PCIe X1 cards to appear on the market, the PowerColor Theater 550 PCIe.

The MyHD and Fusion5 cover the "everything plus the kitchen sink" range of tuner cards, while the Theater 550 is more focused. Where the former offer QAM decoding, HDTV, and digital and analog capabilities, the Theater 550 is an analog-only card. At first, it might seem like this is an unfair match-up, as we have HD capable cards going up against a card that only handles SD analog TV. Unfortunately, reality tends to make the importance of HD functionality less important than most people would like, and the ability to receive and record analog channels well may actually be the more important factor for most people.

It's entirely possible that there are areas where most channels are available in HD, but at least in Washington, the options are rather limited. The major networks all have HD channels - ABC, CBS, Fox, and NBC - but the amount of actual HD content is relatively limited. The USC games for most of this season, for example, were not available in widescreen - only the recent Bruins game was in HDTV. The vast majority of programming is still standard TV upsampled to HD resolutions. Generally speaking, if a broadcast isn't in widescreen format, it's not truly HD (though it could still be Digital TV). ESPNHD SportsCenter broadcasts provide a great example of the difference between native HD and upsampled SD, as the program contains both types of content. Watching a clip from a widescreen NBA game followed by another clip from a different game that is upsampled SD shows a dramatic loss in quality for the latter.

First, let's answer this question: Why is QAM decoding important? For those who live in areas where "terrestrial" or OTA (Over The Air) broadcast reception is poor or downright non-existent, cable or digital satellite is generally required. Cable companies use QAM encoding on their digital channels, and while no cards currently support playing encrypted QAM channels, being able to record/timeshift the unencrypted channels is a definite plus. Depending on your location, OTA Digital TV reception can be easy to get with something as small as the pictured Silver Sensor antenna, or you may need a large roof-mounted antenna with a signal amplifier. At my location, a small indoor antenna is not sufficient for receiving OTA DTV, and while a larger antenna mounted on the roof might work fine, that's often not an option on rental or apartment housing. Besides, there are certain cable channels that I would want regardless of how good my OTA DTV is, like ESPN, Discovery, Cartoon Network, etc. Since I'm already subscribing to a cable service and since OTA reception is a problem without investing quite a bit of time and money into a better antenna, that makes the capabilities of the Fusion5 and MyHD all the more interesting to me - and hopefully some of you as well.

I've been using all three cards for several weeks watching and recording broadcasts and now have a pretty good feel for how each performs, where it excels, and where it falls short. Initial impressions on some of the cards changed quite a bit over time, due in part to the learning curve associated with the technology as well as some hardware and drivers/software updates. Some problems that, at first, seemed like deal breakers ended up having a solution, while other areas that appeared to work okay ended up causing difficulty later. There may be areas that I overlooked, as I don't purport to know everything that there is to know about TV tuners. However, if something is difficult enough that I can't find a reasonable solution within several weeks, that's going to be a problem for many consumers. Let's see if one card can emerge as the clear leader, or if they all come up lacking.

We'd like to thank Digital Connection for providing us with the MyHD MDP-130 and Fusion5 Gold cards for testing. They are one of the few places to carry such cards, but they're reasonably priced and knowledgeable. They answered many of our questions and helped to give us a better understanding of the various software and hardware options. They have quite a bit of information on HTPCs and HDTV accessories.

    First off, thanks for the article. I have been spending quite a bit of time with various HTPC components over the past few months/years with HD capture cards being the one big hole in my research. Your article definitely helped clear up a few questions I had about the MyHD and DVICO cards. Thanks for that.

    I am still slightly confused about the functionality of the MyHD card though. You mention when switching to "HD" mode on the card it "bypasses the graphics card and uses the output of the MyHD card instead." Is this the *only* option for outputting HD, or can it be output directly from the graphics adapter without using the pass-through? If you can output directly via the PC graphics card, is the decoding still done by the MyHD hardware, or is it then the responsibility of the CPU/Graphics card? With old school MPEG2 decoder cards that worked via pass-through (like the Sigma Designs Hollywood+), the card could only output via its own video output. So if you wanted the output of your graphics card and MPEG2 video decoded by the H+ on the display, your only option was to use VGA pass-through. Just curious if this card works the same way.

    One tip on getting HD output from your graphics card - in my experience a little utility called powerstrip ("> is something you simply cannot do without. Powerstrip offers fine tuning of your video way beyond what you get from the card manufacturers and it operates independently of the manufacturers drivers so you won't get all those annoying issues with the resolution bouncing around when rebooting and such - at least once the application loads (your resolution might be screwy until you log in to the box and powerstrip kicks in though.) I've been using it for years to get HD resolutions out of my cards. The most useful resolution for me - 960x540 (or some derivative of to accommodate for overscan) output in 1080i. My TV isn't capable of 720P and, as you mention, 1080i is terrible for outputting anything but video. But 960x540 (essentially 540P) output using 1080i timing is crystal clear and rock solid with both text and video. I am at a loss as to why ATI and NVIDIA drivers are still painful and limited when dealing with HD resolutions while a third party utility is able to achieve such impressive results.

    On another topic, I think there is another important option to consider that is not mentioned in your article - firewire capture directly from your cable box. This option can capture both SD and HD video, provides quality at least as good as any of the tuner cards and is much less expensive (possibly *free*). The beauty of firewire capture of analog channels is all the hard work of encoding is already done for you in the cable box - resulting in virtually zero overhead for recording. Of course, the PC still does have to decode the MPEG2, so if you want to watch HD you will still need some horsepower. However, if you don't care much about HD, you can get away with some VERY low end hardware - especially if you've got a dedicated MPEG2 decoder. Using firewire, I've been able to capture and playback smooth SD video on an 330Mhz Pentium II paired with my trusty Hollywood+ card. Of course as always there are a few caveats to firewire capture.

    First off, your cable company has to offer a set top box with firewire output enabled. I've got no idea how common this is, but my cable provider (Comcast in Burlingame, CA) provides a Motorola 6200 with active firewire ports when you subscribe to HD service, which costs $5 a month. If you’re already paying the $5 a month for HD, your cost is zero. I have always subscribed to HD so I have no idea if this box would be provided to non-HD subscribers. Also, rumor has it there is some FCC mandate that requires cable companies to provide STB's with firewire output enabled, so you might even be able to get one of these boxes just by calling your provider and asking for one. Also, take in to consideration that you would need one STB for every channel you wanted to access simultaneously. So if you want to record one channel while watching another, you need two STB's - not quite as simple as splitting your cable line to multiple tuners and could incur additional costs.

    Second, depending on your provider, firewire capture will most likely only work with non-copy protected channels. This is thanks to a DRM scheme known as 5C. The net net of 5C is that if the device connected to the STB is not 5C compliant (which your PC firewire port is not), the cable box will only allow channels which are allowed to be copied freely (most likely broadcast channels only) to be output via the firewire port. I have read that cable providers in some areas have not turned on 5C content protection yet, so you can get every channel via firewire, but rest assured they will at some point. As I only subscribe to basic cable I cannot comment on whether pay channels are accessible via firewire in my area. The solution to this of course *might* be when cablecard finally comes to the PC, but we'll see if that ever happens - even if it does, I'm sure the devices will implement 5C properly so you will only be allowed to record shows the provides want you to - and other restrictions such as the number of times you can copy a show will be enforced - but these restriction will also be enforced on all DVR's at some point so at least PC capture solutions will be on equal ground.

    And finally (for those of you still with me) setting up firewire capture is a royal pain in the ass. I definitely wouldn't recommend it for the non-technically inclined, but if you are willing to invest the time, I've been able to get great results with both SageTV on Windows and MythTV on Linux. It is also possible to configure firewire capture with MCE but, as far as I understand, it is a bit of a kludge in that you need an analog tuner for every firewire device you want to capture from, even though you aren't using the capture card. I have no experience with configuring MCE with firewire so I could be completely off base here.

    For those who are interested in pursuing setting up firewire capture and/or HD output from their video cards, is definitely the best place to start. I'd also recommend checking out the forums for SageTV if you want to pursue that option, the forums at for getting MCE running with firewire, and"> for a great "how to" on getting MythTV up and running, which includes info and further links on both firewire capture and HD output.

    Great post, nino!

    I actually have thought about the firewire aspect, but I didn't mention it as I haven't actually attempted it yet. Everything I've read points back to your one comment: "setting up firewire capture is a royal pain in the ass". LOL - and that might be somewhat understated. Firewire also doesn't allow you to do the tuning on the PC, as I understand it: the STB has to be tuned into the channel. It's more like using an old VCR to manually record something, but that's still better than nothing, right?

    For the MyHD card, it does hardware decoding and outputs its own signal in bypass (HD) mode. It appears to be the straight DTV content, which is a good way of handling that I think. The card has an overlay mode that shows a preview of the content in a window. Due to the PCI bus bandwidth limitations, though, it is limited to 720x480 resolution (at 30/60 FPS depending on how you configure MyHD). I mentioned this above, as basically 720p and 1080i uncompressed signals can't be piped via overlay since they contain too much data.

    Thanks, Jarred. Not bad for my first post, eh? :) I've been reading Anand on a regular basis for years so I guess it's about time I contributed something to the community!

    As for channel changing, it is now supported via firewire, so no need to do anything manually. Firewire capture works just like any other tuner in SageTV or MythTV - just a little trickier to get setup.

    Ah yes, it makes sense the MyHD card couldn't decode and then pass the video via PCI due to bandwidth... Thanks for the clarification

    On another note - After taking a second look at the article, I found the results of Digital TV performance very confusing. My understanding is that a digital stream is already encoded and compressed, which you also mention in the article, so I would expect the only overhead when recording - assuming you are not doing any transcoding - would be writing to disk - which I would expect to not be much overhead at all. Since the real work with a digital stream is in decoding the stream for playback, that's where I would expect any significant overhead to kick in - at least when doing the decoding in software such as with the Fusion. However, unless I'm misinterpreting something, the Fusion graphs tell a very different story. I am confused even further by how DxVA could affect the performance of capture, again unless there was some trascoding or some other processing going on.

    In an effort to figure out if I was misunderstanding something I did some testing with one of my boxes (a 2.4GHz P4) and the results are much closer to what I would expect. When capturing via firewire (I'm using VLC media player for the capture), my CPU usage hovers between 4% and 10%. I have VLC saving the stream as PS, which is about the only work I would expect the cards to have to do when capturing a digital stream. So where is all that extra overhead coming from?

    When playing back the stream on the same box (I am using the NVIDIA PureVideo decoder on an ATI Radeon 9800 Pro) my CPU hovers between 25% - 35% usage with HW acceleration enabled. When I disable acceleration, CPU usage shoots up to about 80% and over 100% with lots of motion, resulting in choppy playback.

    On a side note, these results are with HT disabled. I was originally testing with HT enabled on my P4 and it *looked* like the CPU was only sitting at about 40% when playing back with no acceleration, so I couldn't understand why playback was getting choppy. As soon as I disabled HT it became clear the CPU was over taxed.

    The only conclusion I can come to is something is misbehaving when capturing with the Fusion - either the driver or the capture software. Thoughts?

  • JarredWalton - Friday, December 9, 2005 - link

    I probably didn't make this clear: "recording" was really "watching and recording" - basically a worst case scenario. I believe both the Fusion and MyHD can be setup to record a channel without displaying the content, in which case the CPU use drops to 5 to 10% or something. Basically, I was watching a channel and then I would press the "record" button.

    I'll have to give Firewire a shot in the near future - of course you need to have a digital cable + HD STB in order to capture that way, which is $25 a month extra over the cost of basic cable, but I have that regardless.
  • nvmarino - Saturday, December 10, 2005 - link

    Gotcha - now I understand the numbers.

    For cable service, the a bare minimum is basic ($12) + HD ($5), at least in my area - bringing my grand total to $17 hard earned bones a month. Comcast doesn't require me to order digital to get HD. Of course I'm only getting very basic service but as long as I get football and Lost in HD I'm happy as a pig in sh.... I spend much more time in front of the PC than the telly anyway which is how I justify paying nearly 4x that for my broadband connection. :)

    Also, my recent testing uncovered something I was unsure of earlier. I can capture pretty much every basic SD channel via firewire, but I can only capture the major broadcast networks in HD. ESPN HD, INHD, and Discovery HD, for example, are DRM'd so no FW capture is possible.

    Here are a few pointers that will hopefully save you (or anyone else who wants to give FW capture a shot...) some time getting started.

    The firewire drivers can be downloaded here:">

    Once you get the drivers installed, I've found the simplest way to test is to use VLC (download here"> to either watch or capture the stream. Once you have VLC installed, you can watch the stream like this:

    File --> Open Capture Device

    "Video device name" --> click the "Refresh list" button

    In the "Video device name" dropdown, you should now see two options for your STB, a "tuner" device and a "Panel" device. Choose the "Tuner" device.

    Click "OK" and that's it. If all went well you should be watching the firewire feed on your monitor. Oh yeah, make sure the STB is tuned to a basic channel so you don't have to worry about 5C DRM.

    One thing to consider - as far as I know VLC doesn't support DxVA so if you're not on a beefy box, playing HD streams directly in VLC will be choppy.

    Which brings me to my next topic - capturing with VLC...

    Follow all the steps above except clicking "OK".

    Once you've got your tuner selected as the video device, check the "Stream output" box and click the "Settings" button.

    In the settings screen, check the "file" box and put the file where ever you want it, just make sure you save it with a .mpg extension

    Click "OK" and "OK" and now you're capturing!

    To stop capturing, just click the stop button on VLC.

    Now, to play back the capture, I'd highly recommend the NVIDIA PureVideo decoder - even if you have an ATI card. You can download a 30-day trial here:">

    I've had mixed results with other decoders handling an HD capture properly, but I'm sure there are others out there that would work as well.

    Once you've installed the decoder, you should have no problem playing the .mpg file you captured in Windows Media Player.

    That's about it for the easy part! You're on your own from here. There are instructions for getting FW working in MCE in the driver download package, or you can view the readme directly online here:">

    And for SageTV, you can find an excellent setup guide here:">

    Good Luck!

  • JarredWalton - Sunday, December 11, 2005 - link

    Thanks again! I'll be giving that a shot in the relatively near future. (Got a few other articles to finish first.)
  • JarredWalton - Wednesday, December 7, 2005 - link

    You can download some demo files to test out how the DVICO card would fare on your PC if you want. A reader sent me this tip.">Here's the link, if you're interested.
  • xtknight - Wednesday, December 7, 2005 - link

    Great review, I enjoyed the downloadable stream clips from all the cards in the different modes.
  • JarredWalton - Wednesday, December 7, 2005 - link

    Last I checked (this morning), about 125 people had downloaded the video clips. I'm actually curious to what the readers feel about using BitTorrent for this. It seems like a natural fit to me, as even a fast data center connection can be overwhelmed by a bunch of people downloading video clips. How was the speed? Did you like this? (Maybe we can get some sort of Torrent server on an AnandTech server in the future so that I'm not using my home network. LOL)
