I have a question about a 2 receiver setup.....In my new apartment the people before me left a DISH 500 with the DP Twin that combines 110 and 119 into one cable into the apartment........I have a 722 and a 211k and will hook up a wing dish at 61.5......I also have a DP 34 switch......Now can I take the 1 cable thats there from the DP twin and the cable from the 61.5 slot into the DP 34 and then run 2 cables to the 722 for both tuners and 3rd cable to the 211k will this work?
