netflix allows you to keep DVDs as long as you want, so you can watch them whenever, and however many times, you like. without paying extra fees.
having them die after a certain amount of time would ruin this, and its one of the reasons i use netflix. if i get busy, i can watch the dvd later. if i realy like something, i can watch it a few times. we got the incredibles on DVD one week for the kids to watch and they loved it, i probably ran the thing a dozen times over the next couple of weeks because i kept forgetting to pick up our own copy.
i wouldnt have been able to do that with EZ-D once id opened it. it would have been useless after a couple of days, whether id wanted to see it again or not.
bah to that. ive also started DVD series of tv shows and taken a few days to finish them, this would make that impossible.
