I am new to the board and need some help selecting a rear projection HDTV in the 42-50" range. I have looked at some Samsungs, Toshiba's, Mitsubishi's, etc., but get more confused as I look. Can someone give me some insights on what brand is better for the price? Most have similiar features, but the Mits seem to be about $500 more in price. Also, I have seen some stuff about DVI. Can someone also tell me what that is about and how it is used? I appeciate any help you can give me. Thanks.
