Somehow my 15 month old go a hold of my Tivo and changed a setting, causing my Mini that is connected to XL4 to use a tuner for watching Live TV. This is not how I wanted this setup, because we never watch live TV, only programs that have been Tivo'd. In the setup guides it states from the settings menu, under settings under cable card and devices, enable Live TV viewing. However that is not an option, and that is the way to turn it on....not off! Anybody have an Idea? I hate calling customer service, it takes way to long on the phone.
