[movieaholic]

Im running windows xp on a celeron 2.20 processor with a intel 3d extreme graphis card when i load a movie into the player the sound is great but there is no pictures these are just standard mpeg 2 and mpeg 1 movies also tried some divx to same thing sound but no picture. Went into preferences checkmarked all the format and clicked on register and still nothing anyone else having this problem. Ps all the movies play fine in real player windows media and divx pro.
