I think FlexView is a good idea but has a few drawbacks.
1) HD. I have not seen any FlexView titles in HD. I don't want to watch movies in SD on my HDTV.
2) Allow rentals to be upgraded to purchases. Many times I may rent a movie either because I'm not sure that I will like it or I might not watch it more than once. It would be nice if I could rent a FlexView movie at the cheaper rental price and then if I decide after watching the movie that I would like to purchase it, I can purchase it and get the rental price credited toward the purchase price. So if for example a movie costs 9.99 to buy and 2.99 to rent, if I rent it first and then decide to buy it, I would only pay the remaining 7.00 difference.
