App Dynamic, the company that brought AirPlay to the 1st generation Apple TV, has just released Remote HD plugin 5.0 featuring an all new AirPlay upgrade. The 5.0 plugin breathes new life back into your old Apple TV with iOS 5 and iTunes DRM-encrypted video support. The update does not include mirroring or HTTP live streaming over AirPlay.
