For some reason I can't Paly Movie files unless I grab the window and move it back and forth? The movie will play for a second or two and then the action on the screen just stops but the file and sound continue to play, however if I grab the window and move it back and forth the movie will play as normal, but a bit slow. any ideas? I had Media Player 7 and upgraded to 9 to see if it would fix it but it didn't. Any help is most appreacited. Thanks.
