I am running the new knoppix dvd 5.1 and have problems watchin movies or any type of multimedia using my onboard vga graphics. MPlayer doesn't run aswell but gives the error "Error loading the output device -vo". Kaffeine runs but starters (breaking motion) with lagging audio. Amarok and XMMS run perfectly.

Please inform me on how to adjust the settings to allow proper viewing ( I never had a problem running knoppix 4.1 and the graphics were perfect)
