Apologies if this is answered in an existing thread - my searches didn't find them. I just had a nice installer come out. He installed an HR-34 in an upstairs room previously devoid of DirecTV service. Downstairs, I have 3 HR-2x DVRs (all in the same room). He did whatever was needed to get everything working with a single wire (SWIM, right?). But he mentioned that he configured things so that the downstairs area supports a max of 6 tuners, and upstairs supports 5 tuners. I didn't think much of it, but now that I'm thinking more, what would be involved in being able to move an HR-2x upstairs, which would be 7 tuners? Is that something I could adjust, in other words?
