I have a Roamio Pro and 3 Minis. Twice now I've noticed that 3 of the Roamio's tuners are in use by the Minis even though the Minis have not been used since yesterday. I can walk around the house and release them by hitting the Tivo button, but aren't they supposed to release by themselves after 4 hours??
By the way, this seems to only happen on occasion….most of the time they seem to release just fine.
