Ed,

It depends on the aspect ratio of the movie you are viewing. Your 16:9 TV has an aspect ratio of 1.78:1. So for any movie that you view with an aspect ratio of 1.78:1 or less you will have no letterboxing (black bars). If you view a 1.85:1 movie you will have very small black bars and if the aspect ratio is even greater (i.e. 2:35.1) the black bars will be larger still. If you are viewing a DVD be sure to set the player to output to a 16:9 TV.
