Hardware MPEG2 TV Tuners Compared 266

Posted by timothy from the baby-I'm-tuned-to-your-wavelength dept.
EconolineCrush writes "The Tech Report has put together an intriguing comparison of TV tuner cards with hardware MPEG2 acceleration from ATI, eVGA, and Hauppauge. The article examines CPU utilization for typical PVR tasks and highlights some very apparent image quality differences between the three cards. Testing was apparently done with Windows XP Media Center Edition 2005, but does anyone have experience with the cards in MythTV?"

    An interesting article, to say the least. I'm somewhat surprised that MPEG4 encoders haven't started popping up, though. MPEG2 hardware has been around since the days of the original Pentiums, but Hauppauge has had things pretty much sewn up. Not because Hauppauge's hardware is that much better mind you, but more because the market hasn't been that big. Video files (especially MPEG2) have always been very large. Computers have only had enough capacity to deal with these on a regular basis in the last few years.

    Now for just a generic TV Tuner, there are other options besides Hauppauge. *However*, almost all of the successful TV Cards use the same Brooktree [brooktree.com] (now Conexant) chipset. This has meant that the quality of the card drivers has been something of deciding factor, which Hauppauge always seemed to do a better job of until recently. Now with "digital convergence" on the horizon, suddenly everyone and their dog is producing usable drivers for just about every OS and settop box in addition. Which, of course, was made easier by the fact that they all use the same chipsets.

    On another note, a purple PCI card?! These guys are just going nuts with their solder masks, aren't they? As if there's something wrong with the color green. (Must be too 1980's.) If they *really* wanted to do something different, they should produce a transparent card with the interconnects lined with a cool color like red. i.e. Make it look like something out of Star Trek or something. :-)

      Hauppauge always seemed to have better drivers? Bwah ha ha. That's laughable. I had one of Hauppauge's earlier cards, the high-end card before the -250 and -350, and the drivers were TERRIBLE. I don't think they ever released Microsoft-certified drivers. In any case, they regularly caused my computer to lock up and even when they worked, they didn't work very well. Now, I suppose it is possible that the drivers from other companies were even worse, but Hauppauge was skirting consumer-protection laws as it was.

      ArsTechnica has some information on this, and on how to use third-party drivers, which can make things much more reliable. I cannot immediately find the article, however.

      According to Hauppauge engineers, the reason they don't release an open source linux driver is precisely for this reason. They feel that their edge over competitors is in the tuning of their driver. Even so, by sniffing the I2C bus on these cards you can pretty much figure out what their driver is doing, which makes this moot (The PVR-150 IVTV driver is rapidly being developed now and is quite usable under MythTV).

    Here's the conclusion for all of you latecomers:

    "Hauppauge's PVR line of cards has held the crown for hardware MPEG2 TV tuner cards for the past few years, and while the PVR-150MCE l.p. has low CPU utilization and the quickest initialization and channel change times, its image quality is clearly lacking. The bundle could also use a DVD decoder to meet Media Center Edition 2005's compatibility requirements. Still, it's the only true low profile card in the round-up, and at $67 online, it's certainly affordable.

    The TV Wonder Elite is a new contender in the hardware MPEG2 TV tuner market, and ATI has packaged the Elite as an all-inclusive solution that comes with everything you need to transform your PC into a personal video recorder. With low CPU utilization, good image quality, and an excellent remote control, it's a pretty slick solution. However the bundled PowerCinema software seems like a step backwards from ATI's old Multimedia Center, and it doesn't even come close to the functionality of Media Center Edition 2005. At $133 online, the TV Wonder Elite is by far the most expensive tuner in this round-up. You get what you pay for, though; the remote alone is worth $50.

    eVGA NVTV April 2005 Surprisingly, the best image quality comes from the least expensive tuner, eVGA's $65 NVTV. The card's bundled NVDVD decoder also makes the card ready to run with Media Center out of the box, provided you have a DirectX 9 graphics card. That's something the other cards lack. The NVTV does have its shortcomings. The card's CPU utilization tends to be a little higher than the others, although not by a significant enough margin to cause concern. The driver bug that plagued our Athlon 64 test system is also a cause for concern, although the card had no issues with our Intel test platform.

    Overall, it's hard to come up with a verdict. The PVR-150MCE l.p. is easy to discount due to its comparatively poor image quality. Although the TV Wonder Elite has great image quality, works flawlessly, and comes with a swanky remote, it costs twice as much as the competition. The eVGA NVTV, which also has low CPU utilization and great image quality, runs only $62 online and comes bundled with the NVDVD decoder, making it perfect for Media Center Edition and thus our Editor's Choice. Just keep in mind that if you have an Athlon 64 system with a VIA chipset, you might want to avoid the NVTV until NVIDIA resolves its issues with that platform."

    • "The PVR-150MCE l.p. is easy to discount due to its comparatively poor image"

      According to Hauppage:
      "The WinTV-PVR-150MCE has the best video quality of any Media Center TV tuner,..."
      Hauppauge PVR 150MCE [hauppauge.com]

      But its obvious this is not the case when you look at the comparison.

      *sigh*, marketing, go figure.
    • The WinTV PVR 250/350 cards are supported by MythTV through the ivtv drivers: http://ivtv.sourceforge.net/
    • I agree with the article's comments on Hauppauge image quality. I have a PVR-250 (before they added the MCE part) and see much of the same artifacting mentioned in the article. I was disappointed with that. I haven't seen it running on Windows though, only Linux with the ivtv driver.

      I've since bought a pcHDTV-3000 card. Haven't got it running jsut yet due to lack of time, but hopefully I'll be happier with this one.

      Anyone know if there are good Linux drivers for the better cards reviewed here?

    I don't use Myth tv, although I've heard that it's pretty good. I built my own system with a 200GB PATA HDD and a Hauppauge WinTV-PVR-USB2 TV tuner, which is not shown. Using Myth instead of MCE probably wouldn't make much difference in the quality of the encoded video, if any at all, because all encoding is done on the card itself or with software encoders that are not part of the GUI. Myth is just the front end, and is used because it's open source, not for its superior quality. Although I don't use it, Myth has some pretty nifty features like a webserver for setting up recordings remotely, as well as commercial skip and other nice features.
    As far as front ends not provided by MS or linux based, I definitely think that SageTV [www.sage.tv] is the best Windows tv software. It has a great network client app which lets users access the full server remotely, either via a network or over the internet. It's nice to look at and is remote-control friendly. On the other hand, it's current version, 2.2.8, lacks commercial skips and a webserver (although plugins for both are available). Besides that, it's definitly one of, if not the, best front end available for windows, that's not a damn OS. Both missing features listed above are expected to be included in version 3.0, which is scheduled to be released some time this summer, I believe.
    One piece of advice that everyone who has ever bought a Hauppauge TV Tuner knows is that do not use the bundled recording software.

    • There is a full height 150. It came out last month. 150 is the lastest version so it makes sense to review using the 150, but I agree it should have been the full height model instead of the low profile
    • I was thinking maybe the 150 does not do hardware decoding and thus they wanted to compare that to similar cards.
      Whereas the 250 does do hardware decoding to give less CPU utilization.

      Going on memory here, may have my facts wrong though.
    • Oh brother. Because the Tech Report is definitely out to get them!

      Seriously....i thought the picture quality looked like crap on it, and comparing apples to apples?

      So take two $125+ and compare it to the NVCard, omg, those jerks are trying to screw over the eVGA card!

      They are three similar cards (with the ATI jumping out because of the remote and whatnot) with similar features and similar specs, the half height issue doesnt affect the card. If the PVR 250 had a remote THEN maybe I would consider that app
    • To clear up some confusion:
      • The 150 and 250 both do hardware encoding and software decoding. The 350 does hardware decoding. This isn't a big deal, since X (at least with nvidia cards) supports accelerated video decoding under linux. (The most important thing is support for hardware scaling) On the other hand the 350 is handy if you don't have a tv-out port on your video card.
      • The 250 comes with a remote.

      The PVR-250 is a good choice under linux since it works with MythTV and the remote is supported.

    If you use MythTV, an ATI card will not work. I'll go so far as to say that an ATI AIW card isn't reccomended for any Linux-based PVR work. The coders blame ATI, and ATI says "What? We released Linux drivers!". It's a lot of finger pointing, and in the end is just frustrating to any AIW owner, such as m'self.

    The Hauppage on the other hand, is the most reccomended PVR card I've seen - Both on the Linux end and the Windows end of things. It has a built in mpeg decoder/encoder, which allows the systems CPU to focus on things other than converting video for playback.

    I recently came across the Hauppage 350 for $160 [pcalchemy.com] and am seriously considering one, however as we move into the HDTV age, I'm wondering if an HDTV-capable solution [eff.org] might be a better option.

    (Yes, I realize there's PC-based HDTV options, but the Mac link was handy)

      That's definitely not true. I'm currently using an ATI TV Wonder Pro [ati.com] in my MythTV box (Gentoo-based) and it works fine.

      A lot of cards, including the ATI TV Wonder Pro, work via V4L and the bttv [bytesex.org] driver. Check it out. I've found that the card works far better in Linux than it did in Windows!

      Hi. I work in the multimedia department (Theater 550 Pro) at ATI. I also use Linux, and have for years.

      Getting ATI to write an official Linux driver for the Theater 550 will be very, very difficult. We're already a small department in ATI (dwarfed by the Graphics side), and simply don't have the resources for it.

      However, we will absolutely, 100%, offer support to anybody that wants to write an open-source driver for the Theater 550. We've heard a lot of "I'll do it," but when we follow up, there's nothing there.

      So that's the situation. If anybody honestly wants to step up and write a v4l2 driver for the Theater 550 Pro, respond to this post and I'll contact you.

        I'm assuming that you've actually had contact with the GATOS project people, who have actually written functional software to use AIW cards under Linux in the past - right?

        If not, try this:

        Send Gatos-devel mailing list submissions to
        gatos-devel@lists.sourceforge.net

        They're not using V4L2 for AIW, AFAICT mostly because it doesn't exist. I'm sure that if anyone in the community is going to be able to use your information, it's these guys.

        Of course, I can't really imagine that the people running the V4L2 project would turn down support either. Unless it's the sort of support in which they are told that they have to sign NDA's which preclude ever writing any other software again, they aren't really given the information they need, and they aren't allowed to actually implement all the functionality they need to... not saying ATI is going to do that, but it's been known to happen.

        While you're tossing 'em information, try sending them chip docs so that they can get a working driver again for my old 4MB AIW, too. I love that thing.

    I've got an Epia M10K box with a PVR-350 that works like a dream for TV recording and viewing. The built-in encoder and decoder means the processor is barely touched when performing actions with the card. The only draw back is the non-MPEG-2 video/DVD playback. Without unpatched video players you are forced to use the regular x11 output which chews up enough processing power to make somethings unwatchable. There are some hacks for mplayer and xine to work around this, but so far they have had audio delay issues with my current setup or required downgrading the driver version for the card. For now I live with slight frameloss when watching DVDs, but am looking forward to new hacks on mplayer and xine.

Optimal compression for line art is substantially different from that of highly-shaded photographic imagery.

        Unless you want to run extremely low bitrates (fitting full-length movies on CDs, etc), MPEG4 has very few advantages over MPEG2. In fact, it has quite a few disadvantages.

        1) Less hardware support. 95%+ of all DVD players out there do not have MPEG4 capability. But they all have MPEG2 capability, since DVD uses MPEG2.
        In addition to DVD players, there are numerous MPEG2 hardware acceleration solutions for cheap low-cost low-power frontents, such as the Hauppauge MediaMVP, and the MPEG-2 acceleration capabilities of many Mini-ITX boards, along with hardware IDCT and hardware MoComp found in almost any video card.
        2) Lower decoding complexity. Even without the advantage of highly available hardware acceleration, MPEG-2 requires much less CPU power to decode than MPEG-4

        MPEG-4 has its advantages, but it's not always the right tool for the job. In the case of PVRs, it is definately not the right tool for the job.

        Go buy a Hauppauge PVR-250 and any reasonably supported video card (GeForce 4MX boards are cheap, VERY well supported, and have excellent TV-out capability, as a result they're one of the most reccommended MythTV TV-output boards), and slap them in your choice of stable x86 system, basically any one will do. It'll work, and if you follow Jarod Wilson's MythTV guide with Fedora Core (Google it, it's also linked to from MythTV's site I believe.) it's easy to set up.

        I agree the documentation is kind of crappy in some regards for MythTV... Jarod's HOWTO should be linked to in a more prominent location, plus MythTV's lead developer refuses to set up user support forums and/or even link to forums that anyone else sets up, resulting in a mailing list with such high volume that basically no one can keep up with the traffic. :(
        • If you plan to burn to DVD yes, mpeg-4 is a waste, but your using a computer to save to a file, and quailty and space, mpeg4 is better. And if you are only going to store the files, space wise, mpeg4 is much better.

          Right now, the common size for a good quality divx tv show is 350 megs, you can fit alot of tv shows on 1 dvd. And there are DVD players that do Divx now. Or your MythTV should be able to play divx.

          So Mpeg-4 is not a waste for me, and seems to be a very common question.
  • There use to be lots of the 250's and 350's on eBay.
    Not anymore. (gratefully I bought 3 of the "48432" versions for my Myth box.)

    The 48432 is an OEM version that was bundled with HP boxes, if memory serves me.

If you happen to have a power house you can put it in.. a 1.5ghz or higher save some money and go with the pvr-250, your backups will take up half the space and your output should be just as nice.

    I have a Hauppauge Nova USB -T which does digital terrestrial (in the UK at least).
    It has PVR functions and pause of live tv etc. The only problem I have found is it sucks !
    Getting it to work under linux is almost impossible, as it uses a different chipset to the standard analogue devices. As such, it is relegated to use on a Windows machine only. the supplied software *requires* both IE5 and WinDVD 4 to be installed for the tv to work at all. Removing ads is an exercise in futility, because, as the card records straight to mpeg2, if you take out the ads, then you have to resynch all the following recording. This is a problem that gets worse as the recording length increases.
    Also, as I am running this on an old win98se box, I am limited to 4GB filesize. I can live with that as it has automatic file splitting, except, that when I try to use the separate pieces of the recording in software such as TMPGEnc DVD Author, I can't ! Only the first section of the file is recognised, and the rest is refused as being out of spec. Strangely, if I use another piece of software ( Womble mpeg editor IIRC ) to open and then save the same "out of spec" files (that's all, just open then save), TMPGEnc suddenly recognises the files ok.

    Add to this the occasional IE "page not found" error in the TV interface (no, I'm not kidding), and you get an idea of the shite this program represents.
    I did buy a PVR 350 originally, but it didn't work, so I RMA'd it and got this instead....foool.
    I will be getting another PVR 350 as soon as funds allow, then I'll have to get a set top box for the digital broadcasts and feed that into the 350.
    A large part of the decision to get the Nova-t was the fact that the uk authorities are going to start turning off analogue tv broadcasts as early as 2006, ie, next year, but if I can get a set top box feeding into the 350 then thats what I'll do.

    Although video and tuner requirements are strict, MCE is less demanding of CPU power. Microsoft suggests a minimum processor of 1.6 GHz with at least 256MB of ram.

    Anybody read this and think WTF? It's not demanding if you are buying a new machine to run MCE, but if you have an older one machine that you want to convert to be your media center, good luck with anything but a P4 or Athlon XP. With Linux and MythTV, you can get PIIIs and sometimes PIIs to work if you have a card with both hardware encoding and decoding capabilities.

    Since Hauppauge is the veteran in this market, it will be interesting how the newer cards will fare in Linux machines. Although Hauppauge does not release Linux drivers themselves, they at least acknowlege that people are running Linux and provide you with a link. I don't know what the numbers are but I would think that a majority of people buying Hauppauge products run Linux.

    nVidia and ATI might want to take that hint and release Linux drivers for the TV functions. Currently there are drivers for the video cards but the ones for the TV chips are not as mature.

  • In the UK, digital TV is widely available over the air with both free channels and a small number of subscription ones. There are now several cards which can capture the MPEG2 stream directly from the broadcast, meaning no encoding and no quality loss. One such company selling these is Nebula Electronics [nebula-electronics.com].

Only terrestrial broadcasts will stay with MPEG-2, and that's only because ATSC won't tolerate a massive change to the standard they spent more than a decade writing.
  • I've got analog cable, and no plans to upgrade. Does this mean that I need to use an analog card like the Hauppage, and that if I had digital cable I'd need a digital card instead?
    • Most HDTV cards will tune OTA HDTV, but there is supposed to be some kind of protection on most cable HDTV transmission, with the exception of the "must-carry" stations (i.e. local broadcast stations), and those you can pick up with an antenna anyway.
