I'm not an expert with GNOME apps, but if you run

  gstreamer-properties

and go to Video/Default Output/Plugin, you can switch xv acceleration
on and off and see what happens (there is a test button playing colorbars).
(apparently you can also run it two times, side by side, to compare)

But I'm not sure if totem and gnome-mplayer obey that setting.

It could be a bug in the driver. You really don't need a test file,
you can just say that "colors are wrong when applications use xv
acceleration".
But, it may be that the problem is not in the driver, just in the
decoding library the players are using (ffmpeg?).

This is why I suggested a test with vlc. If you can get good colors
from vlc in xv mode (called xvideo in the vlc pref panel), the driver
is ok.

Vlc is just another good player; I personally still prefer
the no-GUI mplayer.

Best regards.
