Hi, i have a trouble watching some H264 videos when using VDPAU acceleration. What happens is the screen gets completly corrupted (gray bars cover the whole screen) when player plays a certain frame in the video. It always happens at the same point of the video, for some videos it doesn't happen at all. I managed to blindly save smesg output to a file when this happened, and it's filled with these kinds of messages:
[ 47.595028] [drm:radeon_cs_ib_chunk] *ERROR* Invalid command stream ! [ 48.303022] Forbidden register 0x0020 in cs at 9 [ 48.303029] [drm:radeon_cs_ib_chunk] *ERROR* Invalid command stream !

I'm using Arch Linux with 3.12.1-ck at the moment, but it also happened on 3.11-ck and 3.11 vanilla.
lspci reports this card name, it's a Radeon 4570: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV710/M92 [Mobility Radeon HD 4530/4570/545v]
I'm using the newest stable mesa 9.2.3 and xf86-video-ati 7.2.0. The issue happens with mpv and mplayer.
