We have an Apple TV, and we all use Macs and iPhones. What's the best way to store our purchased videos so we can watch them on the Apple TV and our various devices via wi-fi? I know there's some storage in the Apple TV, but probably not enough for everything. I'd love to set things up so that we can save everything in one place, and all have access to it. I was thinking of getting an Airport for our backups; could we also store videos and have access to them?
