DISH (and I am sure Direct) has a dual receiver. Works great in our 2011 5er.
We have 3 TV's. The bedroom and the LR can watch different channels at any time. The slide out front bunk house (BR #2) would be watching the same program as the master bedroom or visa versa. The only thing required is to "initially" turn on the bedroom receiver. A dual receiver has "green" and "blue" lights and like marked remotes. They are also numbered; 1 and 2.
Contact your service provider and replace your receiver and presto. fun begins!
