Getting ready to move and need to decide what to do with 3 TiVo HDs I "uncovered." After checking my account, 2 of them show as still having LT service. The other one I can't find the TSN in either of my account (I've managed my in-laws' TiVo account for years). I think it might have come from a friend who didn't need it any more. Is there a way to look up via TSN and then "ping" the account that it is currently registered to? What is the best thing to do with them? I don't think they've "dialed home" in > 1 yr. Guess I should put them on a regimen of doing so to keep any value for the next transfer offer, huh?
