Ozzy & Kschiu,
If you use a fixed screen with a projector it has it's own set of issues. When listening to 2 channel music the screen moves, a little like a drum skin and can screw with imaging. I use a bamboo sash to cover my screen when I listen to my 2 channel system. Use a retractable screen if you can. Some say retractable screens have other issue with video if and when they move back and forth.
