Hi, I'm getting an upgrade from a Single LNB -- installed in March 1998 on one TV -- to a five-TV setup with HD programming on one TV and four single receivers on the remaining four TVs in the house. This is to take place on Tuesday of next week. My question in seeking advice: Would it be worth it to call DirecTV to arrange DVR service? I'm not familiar with any complexities in setting up other than concern for phone line, phone jack, and the specifics of such installation. I hope for feedback. I value any that is forthcoming. Thank you.
