How do I play show from beginning?

I have Samsung Nexus and recorded a show. I have tons of option to lock song, unlock songs, I just can't figure out how to get the show to play from the beginning. I'm at wits ends. thanks.

Hello! Anyone owned the Samsung nexus, and then got a unit that blew it away. REally annoyed with the nexus, the navigations so bad, any better units. anybody know?
