Looks like Tivo rolled out the first of their ‘banner ads while fast-forwarding’ over the weekend.
Now would be a good time to enable the 30-second skip backdoor on your Tivo! To enable the toggle hit Select, Play, Select, 3, 0, Select. This will turn the skip-to-end button (->|) into a 30-second skip button. I’ve had mixed results trying to use it in the past, but now it looks like I’ve got a reason to learn how to use it well.
