are you sure with your GTX VDPAU is not supported. Last release of linux driver (180.35) made 8xxxx supporting VDPAU ? (i have a 8800 GTS512)

He's correct afaik - the 8800GTX doesnt have the required hardware... shame cos its still a pretty awesome card (massively overkill for what is required here anyway - pick up a cheapo 9500 or something)

I don't know how the XBMC backend works, but I don't know that you can test a BluRay disk on linux yet. Correct me if I'm wrong, of course, but I don't think XBMC has bluray decryption built in. I believe if you were on windows you could install AnyDVD which would do the decryption in the background. AFAIK there is nothing like that on Linux - but then again, I've never bothered searching for it.
On another note: has anyone checked their GPU usage while using VDPAU? I'd be curious if the more powerful GPUs are "better" at VDPAU than the weaker ones aren't. That is to say, I wonder if there is any merit to having a GeForce 295 vs. a GeForce Go 7700 for H264/VC-1 decryption.

Antioch : i will use bluray disc as you described. That's avoid noice while playing the bluray disc too. (do not like mechanics noises .....).
I have tested today VC-1 from bluray source, and it works fine. 10-13% of CPU on an AMD 3200+

From what I understand, VDPAU is supposed to support MPEG2. But, in my testing of the latest SVN tonight, playing a DVD ISO doesn't use the VDPAU player. Is this supposed to work, planned to work or have I just grossly misunderstood something? x264 works beautifully, which is really the important part...

motd2k disabled dvd playback with vdpau, mostly because else you couldn't use DVD menues due to missing overlay gfx (aka. the cursor) so it was rather hard to navigate menues.
when this problem is resolved, I'm sure vdpau will be used for all Mpeg* content again
