Advertisements This is somewhat a Series 4 question but I am sure others have tried it with Series 3 / HD boxes. Right now I have a Series 3 with two cablecards from FIOS. If I were to get a Series 4 with a cable card and remove the cable cards from Series 3 could I use MRV to move shows to Series 3? With FIOS the copy protection isn't an issue I know since I have been able to transfer anything off the series 3 to a PC. I am just not sure if for some reason the TiVo would block transfers from a cablecard box to a non cable card box. If I can do this I can have one cable card and save $4 a month but still be able to watch in two rooms as well as record ATSC on Series 3. Oh and I would have lifetime on both so they would be active as far as TiVo is concerned.
