"I wish Directv would call comcast and ask them how they get their DVR'S to work off of one cable versus two....."
I'm sure they already know. Most REAL satellite techs know. Heck, even many a cable dog knows why DirecTV has two lines and cable just has one.
You, on the other hand, I'm not sure about. Why don't you tell us why cable only needs one line whereas satellite typically would need two?
