I always thought that widescreen dvds would be perfectly viewable on my new 16x9 TV but after I rented a movie this weekend in widescreen edition, I'm not so sure. I had big horizontal bars; one on the top and one on the bottom of my newer while watching the DVD. Is there a difference between widescreen and 16x9? Can a movie be full screen and still in 16x9 mode? Frustrated.
