Sorry for the delay with this response, Airplay app on the device needs to be updated, use the one from the DroidBOX Market, my understanding is that your Apple hardware will then talk nicely with the DroidBOX device again. It'll be included in an OTA soon if you'd prefer not to install the APK.
Also for others reading, if you install the iPhone/iPad DroidBOX Share client app from the internal web page, update it from the Apple Store
