I have a new Apple TV, Macbook Air, Apple Extreme Base Station, Gen 3 iPad, and iPhone 4s all running the latest software. My broadband connection (if you could call it that) is 2.5 MB download speed. Streaming videos and music from my iTunes library to the Apple TV is painfully slow. Is the ability to use AirPlay predicated on your Internet connection speed? I am not sure what I need to change but right now it is almost unusable. Any help would be appreciated.
