I work night and when i get home i don't find anything to watch that interests me. I feel i am not taking advantage of what directv has to offer. I have an r22-100 with sd dvr service. What type of receiver do i need that's hd and can provide on demand service, internet etc. Also my hd tv would be in the living room and the computer is in a different room. Do they have a wirless router from the computer to the receiver? Please advise.
