Changing gamma in DivX/SVCD file

Is it possible to change and save the gamma level for play back in a DivX/SVCD file?

I have search everywhere and haven’t found a single program that can do this.

I have some DivX files that have too low gamma and I have to keep setting the display card’s gamma control panel.

install divx 5 (pro?), go to start menu-programs-divx-divx codec-decoder configuration - and you’ll find the settings there.
