I don't know why high level fails in rendering now, with some HD
(720p, 1080i) clips I tried, first 'I' frame picture is already corrupt
in those larger size, Y component seems right but UV is totally wrong,
although the render pattern (you can set INTEL_XVMC_DUMP to get
'intel_xvmc_dump' file on rendering details) is identical in main level.
I'm seeking ways to clarify this problem.
