Pat wants to know if he can use an AppleTV without an Internet connection. Leo says that if he doesn't need to stream anything from the internet, he could still use it in Airplay Mode, or connect it to his network and stream content from there. He may run into some error messages with the Apple TV trying to connect to the internet, though. If he selects any of the internet enabled apps, they obviously wouldn't work. It should work fine within his own network, though.
