This is why I stopped using TiVo. I had been a loyal customer who was very happy to pay a subscription and bought several generations of TiVo boxes until they started inserting ad banners whenever you paused whatever you were watching and then into the UI's menus as if that wasn't enough. I wish I could ban advertising and marketing.
They try to be sneaky about it, it doesn't play them on channels like PBS, nothing indicating it is a streaming ad and you can FF through it
