Yes.I only have one TV and I was running the R15-500 and the R22-100.So i got a wild hair and bought a used HR10-250.The very next day the Tivo getting back with DirecTV is published talk about Deja vu.Anyways didn't have much against the R15 besides the guide not having first air date and I believe that was why it wouldn't do updates for first runs good in series links.I did like you could pause the live buffer in the R15 and the live buffer would expand and the guide speed was fast.
Anyways I kept hearing about this Tivo love and since I never had a DirecTivo thought I would find out for myself.So far it's an interesting format.
