Description Thomas Rohloff 2012-11-08 13:48:11 UTC 
This is with newest version from GIT and kernel 3.7-rc4. if I try to watch for example DVB-T with kaffeine and use VDPAU for decoding my dmesg get spamed with this:
[drm:evergreen_vm_reg_valid] *ERROR* Invalid register 0x84fc in CS
and the TV image is totaly destroyed.

Thanks, the video is still flickering and has some issues, but at least it works. :)
Comment 7 Thomas Rohloff 2012-11-08 16:05:14 UTC 
Could it be that deinterlaceing is bugged? Cause as soon as I enable it the video slows down but doesn't look deinterlased.
