I am thinking of moving to another location within my town. Due to recently adding a receiver I think I am in the throes of another two year commitment. My question is when I move and the installer installs my DTV system in my new home, can he use the single wire setup or do I have to stay with the old two-wire method? If it matters, at my new location I will have (4) HR23s, (2) HR20s, and (2)SD DVR80s. Lastly, is (8) the max number of receivers I can get? As always, thanks for your help!
