Okay, I know this has probably been answered like 10 times before (I did a search and didn't find anything), but why do some HD channels have the black bars on the right and left?!!!!!! You can clearly see at the top of the black bar to the left and right that the program is shot in 16:9! Why would they choose to broadcast the show with the bars instead of showing the whole picture? I don't know too many people that have 4:3 HD tvs! Anyway, that drives me crazy, is it going to go away anytime soon?
