I have had Direct TV for a couple of years and now am moving to a new house. When I called Direct TV they said my HD DVR would need to be upgraded and I have two HD tv's so I ordered two new HD DVR receivers. Like my last receiver, I assume it will take two RG6 lines to each receiver. My question is this, I am running the lines myself and Direct TV is installing the dish. Do I need two lines from each going al the way to the dish, or can I split them in my basement with satellite spliters and it be okay? Any help would be greatly appreciated.
