Re: Freeze/X lockup during VDPAU playback
Can you reproduce this problem with MPlayer? If so, can you post your exact MPlayer command, and upload a copy of the video to the NVIDIA file drop; see the sticky post.
If MPlayer doesn't repo the problem, can you please set up a "netconsole" or serial console. With those debugging techniques, you may be able to catch any kernel log messages that occur when your system hangs; your bug report doesn't appear to show anything unusual.
