AirPlay Issues: iOS 7 iPad to Apple TV 5.2.1 (jailbroken)

Are my Keynote Airplay issues on iPad with iOS 7 related to iOS 7 or an incompatibility with the older v5.2.1 Apple TV software I run on my jailbroken Apple TV. Anybody else having Keynote Airplay issues with latest Apple TV firmware and iPad running iOS 7?
