Did Tivo make a change/update recently that would cause TWO mini's to "permanently" grab two tuners on a Tivo and not release them? It's been about a week now and I have 2 Tivo Premiers and 3 mini's. 1 mini has been off for a while (guest room), the other one in the guest room and the "regular" one were used last weekend over Thanksgiving. But here I am looking at my Tivo and it says only 2 tuners are available because the mini's have grabbed the other two. Well the one in the basement hasn't been used since Black Friday and the other one hasn't been used since last night. ?? Yes, I could power cycle the Tivo itself, but what would cause it to behave this way (Tivo or the mini's?) Software update/change or something to how long it grabs a tuner?
