this may be a dumb question but I just got a couple on new sd recivers and a slimeline 3 dish i want to get a hd reciver and was told to make sure that I have sat 103 but when i go into the menu on the sd reciver I fine sat 75, 95 101, 110, 119 no 99, or 103 do these not show up till I have a hd reciver or am I doing something wrong?
