Sorry, I could not find time for checking the debug files, but now at
least I started downloading them.
In the meantime Libav 11 entered testing and there is a good chance
that the VDPAU related fixes in it solved this bug as well.
If you or someone else having access to VDPAU-capable hardware could
test XBMC with it it would be great.

FFmpeg entered experimental thus I plan providing XBMC/FFmpeg in
experimental, but I would like to know if VDPAU works with Libav 11
first.
