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)

> 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
