I have recently hooked my dish system back up after the charter cable guy cut everything and disconnected it hooking their junk up and i finally got the dvr to work like it supposed to. I cant however get the 422 reciever to operate the other two tvs. Ther is no signal and when i hook the other tv up to the 422 the signal intermittently goes out on the DVR quite often. I used the schematic for the DP34 from dish, ANY ideas on what im screwing up? Thanks
