This morning I was watching a recorded Dr. Oz show (Channel 84 yesterday l pm) and stopped it half way through. When I went to resume the show I couldn't because I got a "Locked by Rating" message (with the number 44 under it).
I went to Rating Lock and looked at the settings. Max TV rating 18+, Max Movies A. I reset to Default but was asked for PIN. I finally rebooted and it fixed the problem. This never happened to me before the update.
