I searched for this issue, so please forgive me if I missed a posted answer. My wife and I NEVER watch live TV, but when the TIVO (TIVO Roamio OTA) is left on TIVO Central, after some time period, it changes to live TV. I would like to stop that. Is there any setting I can affect to stop that? Also, when I select "Guide", a live TV window displays in the upper right corner of the screen. I wish to disable that too. Any way? (This is not affected by the "Video Window" setting in the Settings & Messages, then Settings, then Displays menus. This live TV sub-window always plays when "Guide" is selected, and I wish to disable it.
