all of a sudden today while watching a dvd the screen goes black and the sleep light comes on when i touch the trackpad or press a key the screen lights up and the dvd begins to play again, this is all happening while the macbook is plugged into the mains. have i changed a setting without realising and how can i correct this problem. i have been watching dvds on my macbook for a few weeks now and this is the first time i have had this problem.
