So I have a home with 4 Macs. Each of our Macs have different movies within iTunes that I imported movies into. When my wife and I watch a movie, we turn on our Mac with the movie on it, open iTunes, turn on our Apple TV, find our library on Apple TV, and watch the movie. Here's my question, and excuse my ignorance if this is either simple to do, or not possible at all - we have around 500 gigs of movies in our iTunes library, is there any way to watch the movies WITHOUT iTunes open? Or ideally without the computer open? We don't want to upload the movies to iCloud for space concerns - so is there another solution?
