I've been trying out the new VDPAU support for Radeon cards, and it works fine except for two issues:
1. Occasional system lockup (haven't found what triggers this yet)
2. No WMV3/VC-1 files will play whatsoever.
For every file I get the same thing, mostly black with a few lines of green/purple junk at the top.
01:00.0 VGA compatible controller : Advanced Micro Devices, Inc. [AMD/ATI] Turks PRO [Radeon HD 6570/7570] [1002:6759]
Is it possible to get the driver to stop claiming VC-1 support so that I can enjoy the H.264 acceleration until a fix is in place?
Well known problem, only VC-1 advanced profile (as found on Blueray disks) is supported by the hardware.
