I attempted to change remotes to the same address and I get a message stating. You are attempting to set 2 remotes for the same address you are not allowed to do this.
So I assume that they all have to be set for tv2? Can you expand on your answer as to how to do this? I normally have it set where I can use p.i.p and switch between tv1 and tv2.
Is it possible to have 3 or more 21.1 dish remotes controlling a 722. And if so, how do I do this. I have my receiver in a central location and cable ran from it to 4 different rooms. Does it matter if I am trying to control tv1 or tv2?
