for dvd, all you need is some old p3 700mhz or so, with some old gf1 or original radeon and you will never have problems (even tnt should work fineDiplo said:
).The issue really isn't fullscreen DVD, which can be done 100% on CPU. The issue is decoding 720p and 1080i streams, plus encoding streams in realtime.
Some people don't even have a separate HTPC. They use their primary PC as their PVR, so if you're browsing or playing a game, you want the encoding in the background to utilize as little CPU as possible.

Yes the only issue would be if you wanted to watch a dvd while having a significant cpu usage background task running.

like what? browsing, winamp, access databases, and outlook didn't hurt the p3
all i say is, dvd is a non-issue on any new system. if a p3 700 can handle it, a 3gig p4 has to be able to handle it, too. gpu doesn't mather at all. but if gpu support is there, it has to be able to handle it even more, not?
this is all about hdtv today, wich is a completely different beast.

bether install Folding @ Work.. 100 times the performance or at least make it low priority at home so it gets about disabled if you need the performance..
or at least make it low priority at home so it gets about disabled if you need the performance..You do all know folding at home doesn't really do what they say its all a conspiracy its the NSA using your CPU resources to break the cryptographics keys the warez rings use. A little green man told me all about this so thats why I do seti@home rather then folding.
Gotta say s3 really has done a good job NV and ATI have been touting acceleration for a atleast 2 gens now and S3 is wooping their butts.

Daveperm: on original GeForce MPEG2 playback looks like crap. After I had original Radeon on my primary machine and then bought GF 256 DDR on 2nd machine, I was really suprised how much Radeon's HW iDCT helps to make video stream less blocky. (especially you see the difference in low bitrate MPEG1 and MPEG2 files like VCD and SVCD.)
(all this happened about 3 years ago.)
EDIT: S3's success on video acceleration isn't really suprise. (heh, actually I am on Super Savage writing this right now. really nice image sharpness on 1280x1024@85Hz, thank you very much. ) ATI has very long traditions on MPEG playback acceleration on hardware level, but in driver level since first Radeon came, it has become more or less secondary improvment target. nVIDIA again, has been always strugling on HW video acceleration behind the others. It took all way up to GF4MX on mainstream to get same features on HW as ATI had have since original Radeon. based on specs, GF 68x0 takes pretty much quantum leap on HW side acceleration by providing also partial compression acceleration, but this test makes you wonder, how much CPU is encoding gonna take, if decoding needs 27%...

possible, but smooth playback works on Very Old Hardware (tm).. here we're talking about highest end systems, and people care about dvd playback?!

hello? we're still talking about 3 year old hw that had some blockiness!
