I have read from a couple different places, including microsofts xbox faq, that it might be a bad idea to play video games on a rear projection television because it may "damage" them. Why is this? I don't understand why this might be. I have a Hitachi 61SWX01W hdtv ready set, and am planning on buying an xbox. I can't find anything in the manual advising against video games, but I'm still not sure. Any advice?
