We're looking to pick up an Apple TV 3rd generation, but I have a few requirements/questions: I know we can use the Apple TV software to stream Netflix, iTunes rentals, etc. over WiFi - no extra computer required I know we can use AirPlay mirroring to show exactly what is on one laptop, desktop and menu bar and etc. included What I want to be able to do, however, is pick a single source that's running on my laptop (like a movie playing in Quicktime, or a Hulu video playing in Safari) and stream just that source to the Apple TV. In essence, I want to be able to continue to use the streaming machine for work, email, etc. while the video is playing on the Apple TV. Is this possible? Thanks!
