Have you installed the latest Windows Media Player?

Do you get any errors?

Have you tried 92.91 drivers?

prob is not only with windows media player but every player...
it gives me blank green screen...
ab i havent yet tried this version..
but i dont think thats the prob..
think its time for replacement...
