I am a bit lost when it comes to issue of storage and the Apple TV. I did a quick search on the iTunes Store and found the entire Star Wars collection in HD was almost 30 GB. Am I missing something or can only about 6 movies (probably less with what you get out of the box) be downloaded onto the 32GB Apple TV? Sorry if these are newbie questions but this would be my first Apple TV. I am primarily looking to use it for renting movies from iTunes, perhaps some music streaming, some apps. But thought it would be neat to store digital copies of movies on here. But only about 6 movies for the 32GB model? I'm sure I don't have this right...
