I have a dual LNB dish with only two cables in my house. One cable runs from the dish to the main TV and one cable runs from the dish to the bedrooms TV. There are no splitters of anykind, just two cables running to two different rooms.
My question is how can I hook up my DVR-625 to control both TV's (i.e. TV1 main TV and TV2 bedroom TV using the channel 21-60 output)without running more cable? Is there a splitter/diplexer combination I could use outside the house before the cables enter or on the back of the DVR to get this to work?
