I currently play dvd's using the power dvd 5 software. But recently there has been a problem,film playing slower and sound jumping. Also when I play certain dvd's on the pc I get am error message saying copyright check tv out port, code(F4D41436). I used to beable to play dvd's on media player but it just plays the sound. What could have happened? my Husbands ready to rip the burner out of the machine. I did recently re install xp on the system but that shouldn't make much difference.
