My friend has a DVD problem. The issue is that she can watch DVD movies on her laptop, but when she tries to play them on her tv all she gets is a black screen. She has one video out connection on her laptop and she has it connected to the yellow video in connector on her tv, but the picture is black. She does get audio, but it comes from her laptop because their are no audio out connections on the laptop. She has used several different types of dvd playing software, but she gets the same result all the time. Anyone have any suggestions on how to remedy this?
