Hi guys, I just bought a daewoo 30" 16:9 HDTV, I am little concern about watching DVD on it. When I watch movies on dvd it doesnt fill the whole screen, I have three screen mode on my TV: Normal, Full, and Zoom. In normal mode it gives the 4:3 picture and full mode stretch the picture but I still see bars on top and bottom and zoom mode fill the screen but of course it crops the image. does 16:9 TV suppose to work like this? if yes, then whats the benefit to buy 16:9 anyways, when you have to stretch or crop the image to fill the screen. any thoughts??
