Hey Guys, I have two tivo-HD's and love them! Thinking of getting a premiere. While I wait for the cable card, can I test out my premiere by unplugging one of the cards from my current units and insert it into the premiere? If yes, then is it simply plug and play? The Verizon guy installed my 2 tivo-hd units 2 and half years ago and I've never touched it. But I've always been curious if the card is self-contained, or did he program the card to specifically work that particular tivo-HD, therefore it would be useless in the premiere, or at least it would have to be re-programmed. Anyway, just curious cause I don't want to pull out the cable card from my current tivo-hd and cause myself all sorts of headaches. Please advise, thank you!
