Re: 195.36.24 & Quadro NVS 140M & NVS 135M
It doesnt have to do with RAM. The 135M and the 140M both have VDPAU set A - and not all HD formats play (correctly) on them.
Check the players settings. I use smplayer and it works great with VDPAU.
Test the movie with mplayer to see some debug info (in a terminal):
mplayer -vo vdpau -vc ffodivxvdpau,ffh264vdpau,ffmpeg12vdpau,ffwmv3vdpau ,ffvc1vdpau moviename
