how do I get three remotes to operate on the Dish 625 receiver? I have cobbled onto the line that serves a second bedroom and put the cobbled line in my master bedroom. I bought an additional 132578 EchoStar remote but I can only use either the original remote or change over the new remote. I have different manufacturers TV in each room and would like to have a seperate remote for each room. I would like to use both the RF remotes to access the 625 receiver. Can this be done?
