re: Directv for cable, Cox Internet... One cable jack.

You have to have the DirecTV guy connect the dish directly to a line in your house, not the splitter that feeds the whole house. My DirecTV line comes straight from the dish to a line that goes to a bedroom. In that room is the "main" DirecTV box, and every other room has boxes that pick up that wireless signal.

Cox run from the pole into another line that goes straight into another room where the router is.

So i basically have two lines running in my house, 1 for cox and 1 for directv. Just tone your lines and have directv run directly to a line instead of the main feed that splits off to the rest of your house. Then they cant charge your for running another line or having to drill into your house to feed another line.
