I currently have a TiVo + cable card that is paired with FiOS. I have a second unit on the way. To my understanding, pairing is necessary to view channels that are copy-protected, in the case of FiOS - HBO and Cinemax.
What I'd like to do if possible is pair the existing cable card to the new unit so I can get HBO. Can I just go through the whole process again or do I need to pick up a new card? I don't care about HBO on the second unit and when I do need to use this, can I just move the card to this unit without having to pair it?
