I have a r16-300 and I just installed a SWM (3 lnb) dish. I am trying to find the signal and I get nothing. The only menu that I can pull up has the "Tuner 1" and "Tuner 2" signal strength. This is how it was when my old dish had to send 2 cables to my DVR. From what I understand the receiver is supposed to auto detect the new dish... PLEASE HELP!
