At the QuickTime control panel applet you can select to use GDI-only (no
acceleration). If that helps, then it sure is something caused by the ATI
driver. Also can try the System control panel applet, the advanced options
and at performance settings choose to not use graphics vacceleration at all
(there used to be a slider there, not sure at xp)

Subject: ATI color reproduction problem (Windows)
Hello all,
I have a problem with an ActiveX quicktime movie in my C++
app. The movie looks and plays fine using my on-board
graphics card and on a PCI MATROX graphics card. However,
when I run the app on the same machine using a ATI RADEON
7200 the colors are wrong. No other colors on my screen or in
my application are incorrect but in the movie the colors are
not right at all (black is green, yellow is pink etc). The
problem only shows itself with H.264 videos, and the problem
does not exist when I open the video in quicktime, only in my
app, and only with the ATI card. I have read that ATI
introduced hardware acceleration for H.264, so I thought
maybe that could be the problem. I did a lot of searching and
this is the most relevant article I could come up with:
http://lists.apple.com/archives/QuickTime-Users/2006/Apr/msg00018.html
Unfortunately it was not much help. Does anyone have any
ideas? If I had to guess the colorspace is being read
incorrectly. .. . but that is just a wild guess. If I
manually turn off the hardware acceleration of my graphics
card, then it will display fine. This is not an acceptable
solution, there has got to be a way to just disable hardware
acceleration for the movie.
Thanks for any help
-Greg
