I have been trying to copy this movie and 1click get to 30-50% and stops. I noticed that this movie uses a dual layer format. I tried again and checked off dual layer option. It copied to 100% and then tried to burn but I didn't have a dual layer disk. If the movie is in a dual layer format then it has to be burned to a dual disk, is this correct? I seem to be learning something new every time I burn a movie lately. If I am wrong in my thinking please help.
