    Help guys, i have quicktime 7.3 leopard on my macbook pro, os x 10.5.1

    It can play h264 movies and some others but anything encoded as motion jpeg it sort of just shows a few frames and appears to fast forward through the whole movie? I have quicktime pro and i can't export to mpeg 4 it just crashes, ive tried deleting preferences and a new user account no change, not even reinstalling quicktime 7.3

    anyone else had this? it absolutely sucks!
