I have a toshiba laptop and a newer projector. I can see windows 2000 fine, but as soon as I play a quicktime or real player clip, it only shows the window. It doesn't play the clip. It shows a black screen. I tried changing the resolution to 640x480, 800x600, 1024x768 at a standard 60HZ but still nothing. Any ideas? The laptop is using gforce4 420MX or something like that.
