I just got my new VIP722 installed and am having trouble with tv's connected to TV2 output. I want to have 3 remote TV's connected to TV2. When I had Directv I ran the signal thru splitters and it worked fine now, now 1 TV works fine, 2nd TV gets a black box in it at random times which blocks the bottom 1/3rd of the screen and the 3rd TV gets a lot of snow and you can barely make out the picture. Ive tried using different channels ( I switched from 60 to 33) with no change. any help would be appriciated.
