I've just tested it and setting both the primary and fallback
deinterlacer to none unfortunately doesn't have any effect on the
pixelation issue.

The following sample plays nicely with a non-VDPAU decoder in MythTV
or in mplayer with VDPAU ("mplayer -vo vdpau -vc ffmpeg12vdpau
Kanal4_sample_with_playback_issues.mpg"), but doesn't play well in
MythTV with VDPAU with or without deinterlacers:
