I will be switching to Directv very soon and would like to have all the wires in place prior to the technicians arrival. Can somebody please tell me what i need to have run from the hd boxes, which i will have placed into a room in the basement, to each of the tv's. I have Dish right now with no HD and have those boxes in the basement running to each tv with rj6 cable, but i think i need to have an hdmi cable instead. Please help, Directv just tells me i have to wait for the tech to get here and they will handle it. I want to keep all the receivers in the same room as they are in now. Thanks for any help you guys can afford.
