I have a Westinghouse 32 inch lcd tv and when i watch certain movies (i use my XBOX 360) for example "Cars" there are black bars on the top and bottom of the screen. I thought this was normal but when they have TV's on SHOPNBC, they show cars. They are showing the widescreen version but there arnt any black bars on the top and bottom. What are they doing that i am not? Shouldnt there be black bars on the top and bottom of the screen? B/c arnt they just streching the screen to fill it in?
