I have no existing equipment that I intend to use. Requirements Front Projection HDTV DVD/CD Carousel that holds 100+ discs. 5.1 Surround sound Ability to attach it to my home network so I can play movies, surf the net etc from my PC. I have a cathedral ceiling in that room so I can mount the projector on a shelf attached to the vertical wall so it is "out of sight". I would have the projector screen between the windows. I think I can do a 70in diagonal screen, but that may be too big. I need some suggestions on how to deal with the skylights. I was talking to a contractor who told me of a product that would tint your windows using a dimmer switch so you could vary how dark to make the tint. I can't find anything on it.
