Thanks for reaching out. On YouTube TV, ads air as they would on regular TV. You can always skip ads on the recorded content of your DVR using the player controls (play, pause, fast forward, rewind). Hope this helps!
Great question! Once the show airs, it'll be available in your library if you have it set to record. From there, you'll be able to use the player controls to skip ads. Let us know if you have anymore questions!
