Hm, an update with the original problem of corrupted edges. I just
tried playing video of such a resolution again today, and I'm seeing
the problem with totem-gstreamer, mplayer, and xine.

ii  mplayer-k6     1.0-pre7cvs200 The Ultimate Movie Player For Linux
ii  totem-gstreame 1.2.1-3        A simple media player for the Gnome desktop
ii  xine-ui        0.99.3-1.3     the xine video player, user interface
ii  xserver-xorg   6.9.0.dfsg.1-4 the X.Org X server

Also, if the output size is below about 800 pixels in width, or the
original size is, there is no corruption.

Since all three players show this bug I again suspect it's a bug in
the driver. :|
