did the postprocessing options worked for you?

I didn't try them extensively, but the sharpness seemed to work at least.

Pull latest SVN.

Yea - i dont see much for the noise filter either... it's definitely being turned on though /shrug
WRT the post-processing for xvids, i'll have a think but my gut instinct says no - not possible.

I have the same with VC-1 files. I also have 9400 integrated with 512Mb RAM.
From VDPAU info it shows that VC-1 is supported, however i am not sure if it is really working already with the NVIDIA driver.
If anyone had VC-1 working, please report back.

If the VDPAU postprocessing works without a self decoded stream, so if you could pass a raw videos stream to it than it could work. But we might need VDPAU renderer for that. We still use opengl right ?

Well I got it working and I must say it is pretty impressive. I am playing the "killa sample" at about 2% cpu usage.
I have been noticing a fair amount of crashes though. Never during playback though. Usually it will happen when a movie ends or randomly while the system is idling, ie I leave xbmc running all the time and just turn off my projector. For the last few days though when I turn it back on xbmc has crashed at some point in the night.
Anyone else experiencing anything like this? I am compiling a new build as I am writing this. I will see if the problem continues and if it does, I will post some debug logs. Cheers and thanks for the amazing work!

hmm, whenever i play a h264 video with "auto detect" or VDPAU as the renderer XBMC instantly crashes when i attempt to play the video.
EDIT: i used ./configure --enable-vdpau --prefix=/usr
Trying to compile r17941 and i installed the latest drivers myself.
oh i needed to update my driver :x
anywhozer.. i forgot VDPAU didn't support subtitles (now i'm back on windows with hw decoding and SAA/ASS subtitles )

So this means that I have something wrong with my install or maybe I am just not noticing the difference, but can you confirm if the old brightness and contrast are working too, because mine are not, no change to the picture whatsoever.
How was the inverse telecline? I am excited to try it too, because my tv is 60HZ so this should be great.
EDIT: so I looked up inverse telecine and it's opposite to what we thought, it actually bring down a 30HZ ntsc movies down to 24HZ
"Inverse Telecine is the process where video editing tools reverse telecine process. Basically inverse telecine (or IVTC as it is also called) brings back movie's original framerate from NTSC's 29.97fps to 24fps. "

Brightness and contrast not works, but i never touch those anyway.

Not in XBMC, you're not

Now it's okay! That's great!
As I already told several time, your progress is incredible.
It's really getting stabilized now. I played a half an hour trying different formats and it never crashed.
- Sometime, when I stop to play a video, then resume the play (not start from the begining), the OSD screen stays on the screen.
- I am also not able to play VC-1 videos

Well I've given up, I'm thinking the board I got just can't handle the test vids I'm using even though vdpinfo says it's fully capable of even VC-1. I've tried Hardy, Intrepid, Jaunty, and vanilla Debian with prebuilt mplayer and with the latest svn (which added vdpau support) and xbmc from this thread as well. All combinations exhibit the exact same behavior ....slow and/or choppy playback and high CPU usage.
