The update from 5.1.1 to 5.2 hung (did it over wifi). Unplugged AppleTV, and reran update successfully. Everything else works fine (iTunes sees music, apps all work), but my iPhone 5 doesn't see it for AirPlay. I used the app I'm trying to AirPlay from last week, and AirPlay worked fine, so I know this isn't an app issue. I have a 2nd gen AppleTV, AirPort Extreme, iPhone 5, and iMac. AppleTV is on wifi, and signal is strong. Tried a restart--no luck. Considering a reset. Any thoughts/opinions?
