Can't play SVCD on my comp anymore, help!!!

For some reason i cant seem to play SVCD movies on my comp anymore. It was working fine just before i rebooted. If i try to play SVCDs with Windows Media Player, I can only watch it properly when its NOT in fullscreen mode, when i switch to fullscreen, i get no picture, only audio. With PowerDVD, it doesnt start all, no error msg either. If i go to configuration i notice that "Enabled hardware acceleration" is greyed out, which means i can not select it anymore. I tried re-installing PowerDVD but that didnt seem to fix it. Anyone know what could be wrong here?

I am able to play DVDs with Windows Media Player now, i just had to turn my comp off for few mins lol. Seems like only PowerDVD is not playing any type of media properly anymore. When not in fullscreen mode, it looks like there is a black overlay because i can still kinda see the video being played on the edges of the screen. In fullscreen mode, its just all black. I get audio though...
