I just upgraded to the AT9 dish as I just got the H20. Coming into my house DTV installed a 6X8 multiswitch. I then have 8 runs to my theater room - where I distribute to rest of house. Problem is that on 6 runs work - I can't figure out what the problem is with the other two. I two DVRs,2 standard receivers and a H20 so I need seven inputs. Is it possible to use a splitter or muliswitch just prior to the reciever? I know with Dish you can do something like this but I think DTV units work differently. Thanks for the response.
