Beachbum, if the walls are still exposed and you want to truely future-proof your home, get some 3/4", 1", & 2" interduct and run that to any location that you might want to put a TV or satellite (or Internet connection, for that matter). SmartHome sells
this stuff, but there may be cheaper sources. It cuts with a hacksaw and can be glued with PVC cement to attach threaded nipples for termination in a low-voltage box. Also, it has pull tape run thoughout the interduct, so dragging two, three, or more RG6 cables is no sweat.
That way, if DBS goes to fiber optic cabling in the future, or your cable co. gets their act together and you want to hook up every room, you're set.
