I have two dishes - one 1000.2 with triple LNBs pointing at 110, 119 and 129 and the second one with a dual LNB pointing at 61.5. The cable from the 61.5 goes into the LNB-IN port in the 1000.2 and one cable comes out from port 1 and goes into my DN DVR-622 receiver through a 123254 separator. The separator feeds the receiver through two sat inputs. I want to connect a viewsat PVR model receiver to this setup in addition to the DN receiver. How should I go about it and would I need additional switches etc?
