We have a TiVo Roamio Pro and have been having some issues since the update. If we are watching a show on live TV on the active tuner, that is not currently being recorded, then if we go to the TiVo main screen, either by hitting the TiVo button or the left button, then the screen will go black for a moment, which seems to indicate that the TiVo is retuning to the current channel. At that time everything in the recording buffer on that tuner is immediately cleared. Going back to live TV clears the buffer again. This means we are likely to lose some of what we were watching. If we are watching a show on live TV, and start recording it, then going to the TiVo main screen while that show is on the active tuner will immediately halt the recording, without any notice that this has happened. The buffer will also be cleared both when entering and leaving the screen, as above. This is extremely undesirable behavior. These issues do not seem to occur if the buffer extends all the way back to the beginning of the show at the time we start recording; in that case everything is saved and the recording will continue as it should. These are serious problems that have already caused us to lose several shows we were watching. Are other people experiencing this problem, and is it a known issue?
