So how do you know what Sat you get the signals from? I have no idea where mine come from - and I live directly in the middle of the country (MO) so it could be either one. I have been waiting from BBC America in HD for a LONG time and will be pissed if I can't get it!
menu-6-1-3 should bring you to a screen showing you where you get your signals from under "satellite signal".
