I enjoyed watching Harmonquest, the episodes of which have parts video of the table and parts animated story. It's a comedy show, for the most part, which genre appeals to me. Past, that, I enjoy a good actual play podcast, sans video, like BomBARDed or NaDDPod, both of which are also comedic stories.
Just watching a group play a game can indeed be boring. But if that game is just a format for the genre of entertainment you already enjoy, that's the appeal.
