I have a 500 GB Macbook Pro. I have ripped most of my son's movies to my MBPro and Home Share them through my AppleTV so that I don't have to constantly get up and change the DVD, & can easily switch movies if he loses interest. Right now I obviously need to leave my MBPro on in order to use this method. And even though I have the space available I don't know if I want to store 100's of GB worth of movies on my MBPro hard drive. What I would love is a small device like a Time Capsule or Mac mini (central hub) that I could store all my movies and allow me to Home Share through AppleTV & iTunes. Pretty much exactly what I do with my MBPro (central hub) but just leave it on at all times and always accessible to Home Sharing with more storage space. Is this possible?????
