So here's the quick and dirty of the situation. We have a TivoHD as our main unit, and our old S2 as a backup/ someplace for my wife to record her shows that she doesn't care if they're in HD or SD. The S2's HDD is toast as of yesterday. I haven't really done any in depth troubleshooting on it because it's a pretty old unit. So now we're thinking of replacing our 2 Tivos with one Premiere/ XL. I'm debating whether we need to go with the XL, or if the regular Premiere would work. My questions are concerning my Comcast CableCard. I've been reading, and there seems to be some conflicting info. If I do a factory reset of the TivoHD, swap the card to the new Premiere, then I should be able to get Comcast to pair the card to the new unit over the phone, no? If I do a factory reset of the old Tivo, does it wipe the hard drive? Can I hook up the old Tivo and watch stuff that I have recorded? Easier/ faster to do than transfering stuff around.
