I have a Tivo HD and a Tivo Premiere, with with lifetime. Just 2 weeks ago, when I wanted transfer a recording from Premiere to HD, the Premiere wasn't listed in the Now Playing option. Same with the other way around (although it showed with a red exclamation point and said it couldn't connect or was unavailable). Both connect out fine to the Tivo service, I rebooted both, signal strength is good, and in my account on tivo.com it shows as shareable. I have FIOS with that Actiontec router, but I have made no changes to any settings on it, but could there be some blocking going on with it? I have transferred shows all the time up to this problem 2 weeks ago. Any ideas for me to try?
