Maybe this is already known/just not complete yet, but as I've previously written that r600 -vo vdpau without decode looked OK I ought to mention it as I've just noticed.

1080 height mpeg2 or h264 "internally" is 1088, the bottom 8 lines should be cropped off, which is what -vo x11/gl/xv/xvmc do.

vdpau is not doing this, but is scaling 1088 to 1080.

Depending on the source material this may not be very noticeable, possibly just extra black at the bottom + scale, which is only really obvious with vertres test type patterns. Some h264 I've tried do result in a more irritating distorted green band at the bottom of the picture.
