No video on Youtube an VLC

[darell]

I have a strange problem with my video on osx. I have an Acer (emachines) E520 laptop with an integrated Intel GMA X3100 video card. I didn't get full hardware acceleration for this card, but i have native resolution and everything else works.

 

When i go to Youtube i can hear the sound, but the video screen remains black (or white in Firefox). This happens in all the browers (Safari, Firefox, Chrome) I have installed the latest flash drivers en i tried to start them in 32 bit mode. This doesn't help. The strange thing is, that on other websites (like video.google or vimeo for example) i can watch the video's without any problem.

 

Also when i start a movie using VLC player, the screen stays black, but the movie starts to play and i can hear the sound.

 

I've searched everywhere, but i cant seem to find a good solution for this problem.

 

I'm running Osx 10.6.3 and this is the output for the graphics card:
