I've now made 2 copies of The Simpsons and both are having problems. The movie copies successfully, then burns successfully using Nero and it even plays fine up until about 15 minutes in the screen turns gray and you start to hear the audio from another part of the movie. It does this 3-4 times taking 5-6 minutes to clear each time. I'm using DVD FAB Platinum along with Nero 8
i think there is a dedicated thread just for this movie, try search funtion to find here, welcome to AD.
