I have a SONY bravia tv with an Onkyo receiver and a Panasonic DVD player. Whenever I play a movie in my dvd player, the movie is letterboxed in the middle of the screen. So my movie looks like a thin bar in the middle of my tv. I would expect this on a 4*3 aspect ratio tv but why is it letterboxing on a screen size that is the correct aspect ratio (16*9)
