This is a copy/paste of a bug report i first submitted to mplayer2 developers, here:
http://devel.mplayer2.org/ticket/67

---
Using Linux 2.6.39 with ion hardware and mplayer2 from archlinux packages, i found an h264 stream that, if decoded in hardware using mplayer2, exposes several video glitches.
I remuxed from mkv to avi, but things remains the same.

* Please note that the same file played with vlc exposes the same glitches. *

While if played with xbmc,with mplayer (1), and with mplayer-vaapi(with vdpau backend) (all those still hardware decoded) is perfectly fine.
Decoding it in software also plays without issue, even with vdpau output driver.

Example video stream:

However the bug has been marked as invalid because it seems that mplayer2 was linked versus a buggy libavcodec.

It should be sufficient to rebuild mplayer2 on a recent liavcodec version.
This task depends upon

check out ffmpeg 20110724 with mplayer2

I tried to check out just ffmpeg-git from aur, but libraries has different names, and even symlinking doesn't work.
So in installed mplayer2-git from aur which make even ffmpeg-git and statically links mplayer2 to them.
Now glitches are gone.
I wonder if we have to wait for archlinux to update ffmpeg (?)
