Well, everyone I know owns a 4:3 tv, most of us simply for the reason that we don't have money to spend on widescreen TV's and projectors, and prettymuch everyone I've talked to (this includes some Blockbuster employees), hates those bars at the top and bottom of the screen. I'd rather lose a few inches of unimportant footage for the benefit of not being constantly distracted by the black bars at the top of the screen.
I understand SOME people like the widescreen, but I just find it really annoying. Its like I paid for this TV, and now am being forced to use 1/3 of it's screen! Also, the image is compressed into 1/3rd the space, meaning its even smaller. I have a 22" tv screen, and when the image that COULD be using all of that space winds up using about 7.5" of it, it pisses me off.
I've been told by many people that movie companys are soon not even going to bother MAKING fullscreen DVD's OR VHS copies, so basicly, I and many other consumers no longer have a choice to use the entire screen on our tv's. Talk about letting the consumer decide.
