Thanks for the excellent info. I had no idea what HDCP was.
I've decided that I should go 16:9 and make a wider screen, since I do have the room. According to the projector calculator, I should be able to still enjoy a 96" x 72" 4:3 image if I make my screen 128" wide. I do love watching the old movies.
I know this is kind of in the wrong forum, but I'm thinking that I should be OK with the Panny AX200U rather than the AE2000U, since it fits my budget better, and is probably a bit brighter (I have some ambient light in my room). I know it's not true HD, but I seldom watch TV, and mainly watch DVDs upscaled from a Toshiba A3 player (which I bought after they lost the format war, for $65!) or a Philips 5960. I don't intend to jump on the Blu Ray bandwagon for some time to come.
