Advertisements I currently have a TiVo HD DVR with 2 single stream cablecards in it. Because my other TiVo just died (original Series 3), I decided to replace the dead TiVo with a new TiVo Premiere. As part of this process, I called up Verizon and ordered a new multi-stream cablecard in anticipation of getting the Premiere delivered. (They almost wanted to do an $80 truck roll, but I got them to mail it to me instead.) Anyway, during my call to order the new multi-stream card, I decided to have them actually send me 2 multi-stream cards, as I'm also going to replace the 2 single stream cards in my working (TiVo HD) DVR with one multi-stream card at the same time to save money. My question is this. If I remove the 2 single stream cablecards in my current TiVo HD, and replace them with one of the new multi-stream cards I'm getting (and of course activate the new multi-stream card), will this foul up operation of the TiVo HD? Is the TiVo "married" to the single stream cards in such a way that it won't work if I pull them and stick in the new multi-stream card? Again, this is with Verizon. Thanks!
