The Card

The DualTV MCE fits into a PCI slot and operates alongside your video card much like ATI's Theater 550 Pro. The card is passively cooled and has no external power connections, making installation very easy. It comes with a CATV/TV antenna input, two S-VIDEO and audio inputs, and an FM antenna.



The card comes bundled with all the necessary connectors for a wide variety of home theater and audio setups, as well as a standard remote control for use with Windows Media Center. The card takes a standard single cable input and splits it into two signals internally, and the on board amplifier and splitter ensures better signal quality than having an external splitter do the job. The DualTV MCE's MPEG encoder is made by a company called Vixs, and the two tuners on it are made by Philips. Below is an illustration of the card's basic architecture.


Features

As far as features go, the DualTV MCE is fairly straightforward. It's biggest feature would be the fact that, as its name indicates, it offers dual video in, allowing you to watch and record two programs at the same time. This is essentially what cable services like TiVo and DVR offer, however because it is recording to your computer, the capacity for how much can be recorded and stored is potentially much higher.

There are other smaller features of the DualTV MCE, when used with Windows Media Center Edition, that add to the overall package, such as something called MediaSqueeze. MediaSqueeze basically lets you record live TV at a lower bit rate without a major loss in quality. It also lets you translate video that's already been recorded to a lower bit rate, with 4 different quality settings: fair, good, better, and best mode. This allows you to make better use of your disk space for video archiving. NVIDIA's PureVideo is incorporated into the package, which ensures good quality digital video decoding. PureVideo can be purchased for use with any NVIDIA GPU, but the fact that it is bundled with the DualTV is a good thing. We would like to see PureVideo come bundled with graphics cards in the future as well.

Windows XP MCE

Windows XP Media Center Edition is a version of Windows that offers a variety of audio and video applications beyond what you get with the standard Windows XP OS. An interesting side note is that MCE 2005 includes many of the performance enhancements of Windows Server 2003, so it can actually outperform XP Pro systems by a small margin. The main interface for multimedia applications is easy to navigate and full of options.





Windows MCE is listed as a minimum requirement for the DualTV MCE, and is not included with the card package. Unfortunately, there is no software provided for non-MCE Windows installations. This seems a little strange to us, but our focus for this review is on the card itself, and we will be looking more in depth at Windows MCE in a future article.

    One more thing to note about the AIW cards is that they don't have MPEG-2 encoding in hardware, which means they won't work with Windows MCE


    NOT TRUE. Since Spring 2005 ATI released a new MMC plus encoder which allowed AIW cards (9600 and newer) to be used as a tuner in Windows MCE. However, the enocoder they updated to was software based and caused a delay in the video in MCE as opposed to earlier versions of ATI MMC. Using the Analog tuner with the MMC software the channel change time was less than a second. However, using the card in Windows MCE Caused the channel change time to double to around 2 seconds. As others said, what a poorly written review.

    I'm much more than a HTPC enthusiast, having contributed to the PVR-150/500 driver for Linux as well as MythTV. For me quality is a big issue with these tuner cards and the main thing that can distinguish one card from the other. The review was more of a stating of the obvious-- it has 2 tuners, you can use MCE2005, it records video.

    I'd love to see more information such as:
    -- Framegrabs from videos taken from the exact same source at the same time. I've a couple on my 250/150 comparison page http://capnbry.net/~bmayland/fi/pvr150/">http://capnbry.net/~bmayland/fi/pvr150/
    -- Difficult content. The card touts its 3D comb filtering, show some content featuring high frequency luma to see how bad the rainbows are, show some content with sharp horizonatal edges to see if there is luma sparkles.
    -- How bad does the video get if your source is noisy?
    -- Compare the arguably most popular card on the market, the PVR-500.
    -- PureVideo: How many of the features listed are only available if you have a GeForce 7xxx card?
    -- MediaSqueeze: Real world quality/speed of the MPEG-4 encoding. Can you record directly to MPEG4 if you're only using one tuner?

    Well, I won't be buying this card for awhile-- at least till I find a decent review. Reply

    HTPCnews will be posting theirs in a week or so, I know the guy who's reviewing and I have to say that I'm pretty impressed with the DualTV tuner, I'm going to have to get one. Reply

    Please take this off the site, rewrite it and post it again.

    Not only is it incomplete, it is full of very questionable statements. The whole concept of the article is very flawed. Since you're not using Windows MCE for the AIW (since you say it does not work) and it would appear (nowhere stated!) that you do use MCE for the other two cards, how can you compare the cards, as you claim? For TV tuners the software and its configuration makes the biggest difference, so make sure you are using the same thing!

    For this article to make any sense whatsover, address the following points:
    -- remove the AIW and use a Hauppauge PVR500MCE instead
    -- stick to Windows MCE, or choose another piece of software that works with all cards
    -- rethink your channel switching time statement. It's meaningless under MCE (almost all delay is caused by MCE itself). You will need other software if you want to compare the delays caused by the cards (e.g. it is possible to play console games with Theatre 550 configured appropriately). Again, that other software needs to be the same for all cards.
    -- the useless screenshots (cannot compare an essentially blank screen to a room full of stuff, both compressed probably at the same bitrate). Install two of the cards in the same machine, give them the same signal (after an amplifier and splitter), and take screenshots of both together (something like this: http://tv-plugin.com/temporaries/haup_saph_mcm_com...">PVR-150 vs. Theatrix). If this is too difficult for you to perform, use two computers! The screenshots NEED to have text in them.

    Not much of a review I agree and to use some of the cards they did as well just seems foolish. ATI does NOT have a good reputation in many TV card forums due to software issues or just plain no support for some cards they put out. Hauppauge does well in Europe but falls short in the US when compared to Leadtek. WinTV 2000 is one of the most user UNfriendly apps out, shortcut keys are macros not single keys and their remote works when it wants to even with constant reinstallation of drivers. ATI's PQ has never been what I would want to watch for very long and their cards are constantly recording even with live tv.
    If you want easy to use hassle free tv on the comp then if you live in the US get Leadtek if you live in Europe seems Hauppauge works better. Windows MCE is just a very restrictive version of XP home that adds limitations on recordings and codecs sure it has a nice interface for those who prefer America Online to a regular ISP but it's disadvantages out weigh any of the very few advantages if any it has. HD TV is not going to happen anytime soon for a pc unless you live in a metro area say 30 miles or less from transmitter, yes there are QAM cards but you will only get the local OTA digital channels and perhaps 2 or 3 others, certainly not worth the $150-$300 or more for just the card.
    Now before you go off on me about this you should know I build computers, I put TV cards in just about all of them and I've installed the following, NVidia Personal Cinema, ATI AIW, Hauppuage PVR 150, Compro Videomate Gold +, Leadtek PVR2000, Leadtek TV2000XP Expert and Deluxe, Avermedia 878, Prolink Playtv pro ultra, Prolink TV box, MSI VOX usb, Dvico FusionHDTV 5 RT Gold. I've used the boys as test subjects and they always harp to get their Leadtek back, people who've had the leadtek outside the home don't seem to call back, those who have anything else call.
    Should you want info on TV cards how to solve issues and some reviews I'll give a sight here and hopefully since it's not directly competing with AT they will leave it up www.tv-cards.com, I've found answers there along with interesting 3rd party apps for TV, most of which look oddly alot like MCE but don't have the codec and recording restrictions imposed by MCE.

    My AIW constantly records, but that is so I can pause and rewind live TV. I use to not have this set up (back with Multi Media center 8) and have also set it up with out any space to save on the hard drive.

    I have had large problems with the ATI software, but 95% of them were because they don't support Hyper Threading, so I have to turn it (Hyper Threading) off or the TV player freezes. Does anyone know if this is a problem with dual core processors?

    So how does it out perform Pro? Most OS performance is rated in the options available, since each new OS takes more RAM and processing power. So if MCE has more options, why don't the profession all apps run on MCE?

    As I understand it, there are optimizations that have been made to the memory subsystem and disk controller sections of Windows Server 2003. Patching those into windows XP is rather difficult at this point in time, but MCE 2005 wasn't released until after Server 2003, so for whatever reason it gets the optimizations.

    So why doesn't everyone run Windows MCE? Are you willing to spend another $100 for every computer just to get a slight optimization? Do you think any businesses are interested in running "Media Center Edition"? You can ask Gary Key if you'd like more information on this, as he's the one who pointed it out to me. I believe most of the improvements really only show up in theoretical benchmarks, or in heavy disk access benchmarks. Given that MCE is supposed to handle video files really well, it would make sense for Microsoft to spend more time optimizing that portion of the OS.

    I forgot to mention this, but I believe MCE still doesn't have the ability to connect to a domain controller. For businesses, that's often a critical consideration, which is why most businesses use XP Pro instead of XP Home. (I could be wrong on the domain controller support, but I'm pretty sure that's correct.) Reply
