overlay + conversion to RGB failed

Help !!! I can't read DivX movies.
Messages: Overlay failed -->Display hardware is not capable of color-space conversions, switching to RGB -->BSplayer found a problem & must close.
I have Windows XP, an intel 82815 graphics controller + installed the last Directshow version (directX 9.0) + the last Nimo codecs pack...
I tried other players but it doesn't change anything ... :roll:
Any :idea:

Decrease resolution and refresh rate. 1024x768@75Hz should work fine.

I've switch the refresh rate from 85 to 75 Hz and ... IT'S WORKING !!....
Many thanks Vidric
