My brother just purchased a new Panasonic rear projection tv. It his the 53WX model. Since this is a 16:9 set I am wondering this: When watching a widescreen dvd should there still be a slight amount of letterboxing of the image, or should the image fill the screen totally? I own a Pioneer rear projection set, but it is 4:3 so I really don't have much knowledge about 16:9 sets. Thanks in advance for any help you can give.
