I know I'm showing myself to be a real techno-boob, but could someone help me out? Am I correct in my conclusion that even on the cable company's HD channels, not all the programming is high def? Some shows, some commercials even, look better than others in Midcontinent's Grand Forks area high def tier of channels (the 600's). Is a show really in HD only when it's on an HD channel AND the picture being broadcast carries that little HD logo?
