Hi. I just installed driver 180.25 (64 bits version to go with my Ubuntu 64) + that lovely latest patched mplayer on my system
(Asus P5N7A-VM with geforce3000 chipset + Intel dual core E5200)
Good news are cpu is indeed taking the backseat and lets the gpu do the job
Bad news are : it's not working more than some seconds (15 to 40...) regardless of the source
(tried half a dozen 720p and one hdlite (1440*1080) tvsource, all h264)
needless to say the same mplayer without vdpau codec (-vc ) runs the same files without problem.
when it crashes, I often see that error on terminal
Error 2 at libvo/vo_vdpau.c:1052: 0.000 0/ 0 2% 0% 0.3% 4 0
sometimes I can't even check terminal error msgs as the crash just...hangs the system and I have to reset the computer...
If someone has an idea ...
