I have a Proxima DX3 projector with a TiBook/500. Connecting it to the VGA port, it shows up just like another monitor, and projects fine. However, I want to use it to project DVD video in large scale from Apple DVD Player, and when I open DVD player, it tells me either that it doesn't support the current resolution, card, or driver for the main monitor. Even if video mirroring is off, and the Book's screen is set to what will normally present video, it still gives me the same error. I've tried a variety of screen resolution combos. Any ideas?
