I have a compaq laptop and an apple powerbook G3. They both have Windows Media Player. They both work fine. I can view WMV files on the LCD panel of both laptops, and hear the sound as well. However, when I attach an external monitor to either laptops, or an LCD projector, I cannot see the movie. It is blacked out. I can hear the audio, but can't see the movie. WHY WHY WHY???
