I am a prev Direct tv customer and currently with u-verse and have a dish mounting pole still and all the prev cables run to each room (1 line per room, maybe 2 to the main tv area?) my question IS : If I go back to directv and get a Genie as my main unit and 3 additional boxes to work w/genie in other rooms, will they have to run new (more) cable? Or just use my existing (assuming all is good with it, est 3 yr old cable)
