HI, I had a Directv receiver die and decided to try and hook up my old DSR6000 in the meantime to replace it. I have an HR22 also setup. I am using an SL3 as the lnb/switch. The software on the DSR6000 is 3.1. I am not able to detect any signal on any line, even though my HR22 has no signal issues at all. Was there a software update that was required to use the newer LNB? Thank you very much.
