Since I got the 9.1 update on all my units a few days ago, I've noticed a really odd problem on one S2 (Humax). I have two S2s and one S3. One of the S2s is automatically copying (transferring) shows from the other S2. I have puzzled over how these got there (no wishlists (none) and only 2 season passes and no Tivo suggestions so this Tivo is not heavily used. Tonight I caught it with the blue recording dot (means transfer not straight recording) of a show. There is no info in the recording log about why it is doing this. Has happened 4 times so far since the 9.1 update. It SEEMS to be taking the recordings off the top of the now playing list on the other S2.
