I have to say, I've become addicted to the new rental downloads on the AppleTV. The weekends are now set aside for watching rentals and I've enjoyed everything I've grabbed so far. One thing I have noticed, during the week I browse around the iTunes store looking for something new to rent and then I grab them on Friday night ready to go for the next day. I've noticed that some movies disappear from the store before I get the chance to order them (I know, I should grab them when I see them). Some movies I've noticed disappearing are Saw IV and 300. Just curious as to why these movies are only up for a short while and then taken down again Studio decision or Apples?
