Just downloaded free Express Burn & am having trouble copying a video dvd that my son's school made of his football game. When I open the dvd it plays the video of the game, however, when I try to copy it so that I can burn my own dvd, it copies a Christmas movie called Friday After Next. Am I doing something wrong or is it possible that the dvd that the school used had this movie on it prior to being used for the game video?
