I'm seeing the same, this happens on all videos with a width not dividable by 4. The attached video has 450, I saw the same, reported it to mplayer and got that tip: http://bugzilla.mplayerhq.hu/show_bug.cgi?id=1712 It can also be triggered with mplayer -vf crop=401:300 or similar on any big enough video.
git bisect says: cb06aa32d433f54affe87da2cf964f0308d3c258 is the first bad commit commit cb06aa32d433f54affe87da2cf964f0308d3c258 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Mar 1 22:57:39 2010 +0100 Xv: fixup XvMC on i915 I've accidentally broken i915 xvmc due to alignment constrains that break my assumption that Y-pitch == UV-pitch*2. Fix this up by consistenly using dstPitch2 for the Y-pitch. This also unifies the dst pitch computation slightly, now that the i915 xvmc special case is gone.

Actually, I can't reproduce this in the latest release (2.11.901) so it seems to have been fixed somewhere between 2.11.0 and 2.11.901.
Fixed in 2.11.901.
