OK, so i was wondering if this a true. so an apple tv has 160gb of storage...if i have lets say 300gb of movies and tv shows and ive bought them all on my computer so thats where there stored...in the apple tv you wirelessly connect your itunes libary so you can watch movies from your computer...so what i am asking is the storage on the apple tv is not being taken up unless you buy movies directly from it...is that correct??
