Maybe I'm on the wrong track. Ambient light would not be a problem, but having the screen down all the time might be. My wife watches TV alot and that would mean the screen would have to be down most of the time. Aesthetically, I do not know if I could adjust to that. Also, I would want one of those screens that pull up and mounted on the ceiling thus concealing it when not in use since this will be in the livingroom. If it were just for DVD/movie entertainment, then I would love to have one. That is the main reason that I'm hesitant to buy one. I basically disregarded AVMASTER's comment because I have seen some of the newer projectors at a audio shop. They had a HT setup with a projector -- it was really nice.
