Is anyone else unable to select Apple TV for AirPlay after 5.2 update?

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?
