I just recently installed the optimized driver and it works great. It solved the jittering of my tft screen while playing games.But now when i try to play movies mediaplayer crashes aswell as mediaplayer classic and winamp.. I installed the recent optimized driver. Does anybody else have this problem?

Try to update your sound card drivers or try to reinstall both Sound/Graphic card drivers. Make sure to use DriverCleaner as well.
