Satillite for dumbies

Update - I borrowed a direct TV receiver from a friend who has satellite tv, I hooked it up one at a time to the two coax cables coming in from what appears to be the dish and did get it to lock on and give me all the channels my friend subscribed to. I went from the receiver to TV with a set of AV cables that where already coming from the front TV. It appears when they installed the dish they skipped the factory prewired panel in the cabinet with the DVD and switch box. Not sure what the other coax is? Both TV's work off the antenna through the switch box also DVD player and cable TV works when hooked up at parks. All through the switch box. I think my next test will be to see if I can hook it to the factory set up and get it going through the switch box so both TV'S will get satellite. But at least I know the dish works and I can order my own service.
