I have a samsung HCN4727W, a hughes e86 HD reciever for directv. sometimes the "t" is missing on HDNET logo, like the picture is beneath the border of the screen. normally the edge of the "t" is against the edge of the screen. am I missing and inch all around? Is it the reciever? the TV? or directv? I also notice some of the discovery HD channel logo missing (the small "y" is gone and the large "d" cut in half). Ive had HD for only a few months, been so impressed I havent complained about it but its time to correct it. helpppppppppppppp
