. . . I can just DVR it for free? Help me understand the economics of renting episodes. I can understand it if you throw away your cable box and use Apple TV as a focused substitute for several shows. I can understand it if you view it as the cost of losing ads (though it's easy to fast forward right past them on the DVR). So if I have a cable connection, and I have a Tivo, what circumstance can you think of would make me want to rent an episode?
