Hi, I'm about to pull the trigger on the new Apple TV and I wanted to get a feel for how it'll work. I realize that streaming local content will be through iTunes, so I'll put all of my DVD rips on a spare Dell laptop in the basement. That's no problem. I want to know if the aTV will stream photos from a Macbook's iPhoto library and home movies from an iMovie library. In these situations, I will have the Macbook turned on. Or do I need to have iTunes stream the photos and home movies? Are there issues with having the AppleTV "connected" to many computers (Macs and PCs) at once? Thanks.
