I have DirecTV and I have two DVR's, both will record 2 separate programs at the same time, either TV can watch programs on both DVR's. I have one dish and one coax coming into the 5'er. With the right components and a wiring diagram from Jayco, it wasn't hard to do. No new holes and no additional wiring. Let me know if you want more detail.
