My TiVo box has recently started switching to YouTube when I've left it alone. I switch the TV off but the TiVo box, instead of putting itself on standby, turns to YouTube. Today it did it whilst I was watching the TV.
Welcome to the forum and thanks for your post although I'm sorry to hear about your problem with TiVo switching to Youtube randomly.
I've managed to locate your details and run several checks on the TiVo® box. The test results are all healthy with nothing standing out as the potential cause of this. I'd recommend taking a look at this help article How do I clear or reset my TiVo box? as this may rectify the issue. Your looking to carry out option four which is clear and delete everything but I'd recommend watching your recordings before doing this as they will be removed during this process. If the problem persists we can then look to arrange for one of engineers to come around and investigate the issue further.
Did anybody find out what caused this? Our v6 has started doing the samething. Sitting watching something on playback from myshows folder and all of a sudden it will switch over to you tube then occasionally turns off.
