Introduction

TV Tuners are becoming more and more popular as home theaters and computers start to merge. Already, many countries outside the US are making the move to integrated computer and home theater/entertainment centers in their homes instead of separate components, particularly in parts of Asia where space is limited. Of course, many people in the US are also beginning to see the benefits of combining their TVs and computers into one unit, and it seems reasonable to predict that this will be the norm in the near future.

We recently reviewed NVIDIA's DualTV Media Center Edition TV tuner card, and in the article, we looked briefly at the ATI Theater 550 Pro (again). ATI has had success with their Theater cards in the past, and now they are unveiling a new addition to the series, the Theater 650. This is the newest TV tuner chip/card from ATI, and like the 550 it's still a single tuner card (unlike NVIDIA's DualTV MCE), but there are some new features with this one that set it apart from the rest.

One of the most notable features incorporated into this card is that it has digital capabilities and is one of the first solutions to properly combine digital and analog TV reception, recording, and encoding in hardware in one solution. It boasts much better filtering capabilities as well; for example, it has a new motion adaptive 3D comb filter for better image quality. There are a few other features of the Theater 650 and of course we'll be looking at all of them further in the review.

We've chosen to limit the comparisons to only cards that are compatible with Windows Media Center Edition, in order to keep consistency between TV tuner applications. We will be comparing the Theater 650 to the older Theater 550, as well as NVIDIA's DualTV MCE. We'll be looking at not only image quality, but also CPU utilization between these three cards.

We were very appreciative of all of the comments and suggestions from the last TV Tuner article (the NVIDIA DualTV MCE) and hope to provide better coverage of this card and it's features this time around. Reader feedback is very important to us here at AnandTech and we are very concerned with what our readers want to see in a TV tuner card review. That said, in this review of ATI's Theater 650, we'll be looking at the card, its features and how it compares to a couple of other solutions in both performance and image quality. So without further fanfare, let's look at the ATI Theater 650 Pro.

    Currently own a Theater 550 chipset and i like it much better then my roommate nvidia dualTV one. My question is, can i buy another Theater550 so i can dualTV, would the system go crazy on me? Would like to have dual screen running different sport program at once and would be cheaper for me as well.

    that would work fine

    When is Anandtech going to publish a decent article on TV tuners? In no particular order:

    Why use ATI promotional material that is designed to prove that the 650 is better than the 550? Use your own material if you want a fair test. More to the point, why transcode it? Im sorry, but file size considerations are not a good justification for degrading the image quality <IN AN IMAGE QUALITY TEST>.

    How do you justify adding throwaway comments about equivalence with Hauppage products in the conclusions if you havn't addressed the cards at any point in the review?

    Why have you taken the instantaneous CPU utilisation from task manager and tabulated it? You need to take an average over a reasonable period of time if it is to have any relevance.

    Seriously, there's not enough depth in any area to make the review really worthwhile - you may as well post a single page saying "Look everyone, ATI have sent us this nice new card they want us to plug!" and it would have the same amount of relevance to 99% of your audience.

    Why is there no mention of how this card preforms on DTV, that is its major difference and only really new feature? Am I missing something here? You didn't test the Hauppauge because you have looked at it before. You've looked at the ATI 550 before also. In the earlier test you campare a dual tuner card to a single tuner card rather to the other available dual tuner card. Will ATI only give you stuff to test if you don't compare it to the competition? As you said, Nvidia's card is only available directly from them and at twice the price. The Hauppauge MCE 500 is available anywhere and is cheap. Oh, you have looked at those cards before.

    I can tell you for sure that I am a lot more interested in Picture Quality and functionality than in power consumption or cpu usage.
    Not worthy of AT and its getting to be a habit.

    We transcoded it for your benefit (smaller file to download) -- in our image quality analysis, we used the unmodified output of the cards. Sorry if this was unclear.

    As for using ATI's material, you can't argue with a zone plate. Better is better and worse is worse. Same for the other tests we ran which were designed by SMPTE (http://www.smpte.org/)">http://www.smpte.org/) ... ATI was gracious enough to provide us with these tests we would have otherwise had to purchase ourselves.

    testing the Hauppage card is a reasonable request, but it doesn't change the fact that it was similar in quality and performance to the Theater 550 in previous evaluations. That is perfectly reasonable information to use in drawing conclusions.

    One thing I really hate more then anything is the fact that min reviewer are so lazy in the cheating game by using the PrtScn Button and do not do ture original video RAW decode MPEG screenshot in the rigth application software like Womble MPEG-VCR and always seem to be using MCE DVR-MS proprietary video and audio format carp what matter are they just to lazy in using other PVR software or GraphEdit to get real MPEG files but as we all know that the NVIDIA DualTV is not option with GraphEdit which has no exposes advanced features properties.

    2nd problem as today no body turely using low bitrate under 4MBit/sec which is more reasonable testing to see how well it really dose encoding without artifacts.

    So you wondering why I said cheating well each encoder dose there video difference from each other and there for the decoder filter display difference in case depend on the clean up filter like Deinterlace, difference Enhanced Video Processing Technologies which get apply on top the MPEG Video.

    Now as for comparison.
    Hauppauge, ATI and NVIDIA
    Hands down Hauppauge PVR cards wins becuase of some major reason it has support for more OS then any one eles Windows, Linux, Mac (Apple) and yes even OS/2 Warp or eComStation and has more 3rdparty application support.

    As for a real encoding comparison all test they should done with the fellowing device
    VCR, Stardard Antenna TV, CableTV Analogue/Digital and Satellite with fellowing output source S-Video/Composite and Tuner

    CPU Utilization is really useless becuase all of today Video card are still mostly base on 3rdparty SW-Decoder which mean you still need fast CPU unlike a ture HW-Decoder which provides a real decoding performance unlike today video card which only do part HW-accelerated decoding not full HW-decoding.
    Let say for Example you have Intel P3 800MHz runing 2000Pro or XP with 512MB and you can chosse from GeForce"4" MX4000 or GeForce"7" 7800 becuase you want upgarde your old doggie ATI 3D RAGE PRO 4MB what do you think you see in CPU Utilization from the two card newer card.

    One thing I really hate more [than] anything is the fact that I have to try to read cr*p like your comments, which try to pass off the sh*t in your head for English.
