HQV Picture Detail Test
This test helps determine if there is any sharpening applied to the video, and if so how "clean" it is. Excessive sharpening results in a lower score than more realistic or subtle sharpening. We found that ATI seemed to apply no sharpening at all, while NVIDIA applied a good quality soft, natural sharpening.
On the plus side, sharpening is not always the best thing to do in every situation. In many cases, the creators of the DVD will have already sharpened the video to the level they wanted. In such a case, using the decoder to apply more sharpening would detract from the experience the author intended. Thus, for this test, we are happy to see that neither ATI nor NVIDIA over sharpen, and we aren't really convinced that a higher score always means better quality here. Even in this test, you can see that the difference is very subtle between NVIDIA and ATI. Look at the differences in the bridge especially.

I am looking to build a Media Center PC. I need a card that has a YPbPr input and can be paired with a SB audigy to record the signal coming off my Directv HD Reciever. Tivo doesnt have a PVR yet that can work with this and I was kind of hoping to build one myself. Would this card allow me to do this? If not, what do I need. The MIT MyHD cards will not work as they do not have either a DVI input or a YPbPr input.Thanks.

Hey put the old way of showing benchmark figures, this is too confusing and hard to read!Pastuch - Friday, February 10, 2006 - link
"If performance continues to increase at the rate that it has been, we aren't sure how game software will be able to keep up. We are always happy when we see advancements in technology, but the huge sizes of some of these high end cards make us think better efficiency might be good direction for graphics hardware to move toward."I'm so tired of reading comments like these! Look at the benches of Fear and try to tell me that graphics power is in abundance. You have to buy a $600 graphics card to play the game at a decent framerate on pretty much any LCD monitor sold today. Even if you buy a low end 17 inch LCD you are going to be running 1280x1024 because that is your monitors native resolution and anything less results in a much poorer picture.
With the number of features built into most motherboards I cant see any problem with filling the extra space with graphics cards. You dont need 5 PCI slots. The charm of the ATX standard is and always has been adaptability.
P.S. The price of graphics cards is totally rediculous these days. The cheapest 7800gtx 512mb you can buy in Canada is $899 on sale! The x1900xtx can be found for around $680. I hope Nvidia doesnt continue this crazy pricing in their spring release.

Where does one get the ATI DVD decoder? Does that only come with the AIW cards?LoneWolf15 - Friday, February 10, 2006 - link
It's taking ATI an awfully long time to figure out how to put the Theater 550 on All-In-Wonder cards in place of the Theater 200. Until they can do it, and thus give us hardware MPEG-2 encoding when recording video, I'd rather pay to have both a video card, and a separate tuner card (like my Hauppauge WinTV PVR 150) in my system. The All-In-Wonder X1900 is supposed to be the Cadillac; why are the video recording features more akin to a Chevy?Questar - Friday, February 10, 2006 - link
Is this your attempt at a troll, or are you just uninformed?This card has MPEG 1/2/4 hardware encoding. ATI has had hardware encoding on the AIW card for over a year.

Gee, thanks for your insulting reply. It is possible to be informative without being insulting, you know.LoneWolf (the "troll" who owns a Radeon X800XL and an ATI TV Wonder PCI)

How can you own an X800XL and not know it does hardware mpeg encoding?Questar - Monday, February 13, 2006 - link
Oh, I get it, you didn't get the AIW version.Hmmmmmm....

None of the ATI cards do HW based MPEG2 (or any other sort) of encoding. At least not yet. ATI has demoed their AVC codec, of which the released version of the demo does not actually use the hardware and produce horrendous quality becuasr they skip most of the AVC codec features to attain high speeds.To see this all you need to do is compare CPU load of teh AIW -vs- the ATI 550 Elite and see that the AIW is not using hardware of any kind.
