when I connect my 811 to my Sony 36" direct view via either the component video or the dvi connector, all the images are letterboxed on the top and on the sides. This is true of non hd broadcasts as well as network broadcasts that are supposed to be in hd. However, the high number channels 9500 such as Discovery HD theatre are just fine. I have used hd set-up and chosen the 4:3 aspect ration but as long as I use either the component or the dvi connector is seems that the pixals composing the picture are centered on the screen. What gives?
