I have a VIP722 receiver and had dish set it up for two tvs.Well I changed the 2nd tv to another room, and some how got my cables mixed up, is there anyone who has a schematic on how to hook up the 722. I want to run a primary tv in one room and the 2nd tv in another room. I believe it was setup with the main signal going to a diplexer and then split to a splitter, but I can't quite remember how to get it back to original.
