I am trying out the On Demand tonight for the first time with my Hopper. I went to the HBO On Demand and chose an episode of The Sopranos. It said it was free which I assume is because I am an HBO subscriber. The episode is now showing in My Rentals and when I viewed the info on the episode it has the message "Available to Watch for: 29 days 23 hours". So, what happens after the 29 days and 23 hours? I assume if I wanted to watch it again in the future it would still be free, right? I am guessing it just clears it out of the my rentals section to save on hard drive space?
