ok i have a laptop that has a video out where i can hook up to a tv. i am able to get my desktop an everything to show on the tv screen, but i am not able to play any movie files. i tried using media player to play an avi file, and all it does is give me a blank screen. i tried a dvd wth windvd, same thing. anyone know how to play movies on a computer so that it will show up on the tv screen?
