I have searched for a TV show and it won’t let me watch it online. It gives me the option for OnePass. What does that mean?

This means the show is not immediately available to watch online. However, you can use the convenient OnePass option to set a recording on your TiVo DVR and watch the show at home. Use OnePass to tell your DVR to record all episodes or select Upcoming to see when episodes will be airing so you can select which ones to record or watch live while at home.
