Rentals should be on DVD-RW that you put a credit card hold for the amount of the DVD, say 15 dollars then you rent it (regular rate applies) and return it at will, If video store needs more LOTR TTT they just burn a few more and rent them out; when that demand starts to subside they just burn the latest movie onto those discs, you can hold onto them for as long as you want. Maybe there is a set time before the charge goes through or when you trade in your old movie for a new one, you get the idea
