My dad has a relatively new Dell and running Windows XP. He's been copying some of his older tapes to DVD so he can play them in the PC and sometimes the DVD player says there's no disc in there when there is a disc in there and other times it says drive is full when there's no disk in there. He is copying them on one of those VHS to DVD recorders. Could that have an effect on why sometimes the DVD won't play the movie one day but will play it the next? I don't see though why the DVD player would show disc space full if there's nothing in there. Any ideas?
