I have a lot of home DVD movies that I am converting to m4v and adding to iTunes to view via apple tv. I have so many movies on my little MacBook pro from the itune store and other movies that I am running short on hd space. Without having to get a larger drive, is there a way to store them on an external drive and still watch them on apple tv? I am thinking that I can store them on an external drive and when I want to watch them, I have to import them into iTunes, is this the best solution, aside from upgrading my hd? Thanks in advance.
