streaming TV direct from satellite to computer

EDIT: Actually read the page. This also requires an internet connection and looks like it streams from the internet, not from the satellite receiver itself.

This might do it . . .

DirecTV Anywhere

However, if there were a gizmo that would accept an input from a satellite receiver (RGB, maybe) and make it available as a source on your local network, might work. Take some digging, but I'd bet there's something out there that would do it.
