Advertisements Let me start by saying I know nothing about tivo. I was given an old series 1 non-directv receiver with a lifetime subscription on it(i called tivo and checked). I have directv and no cable options where I live. Will this work if installed after the directv receiver and before the tv? Also If I hook this up do I have to pay directv even though the tivo already has lifetime on it? It is a tivo model ptv100 (also says model philips hdr112). Can the software on this be updated to work with directv? Any help would be appreciated.
