During playback, the Apple TV regularly stops to load and buffer the movie.
  1. If the buffering did not happen before, other software or another device might be using the network, leaving too little bandwidth for Beamer. Please make sure this is not the case.
  2. If you have an older model Mac (circa 2008/2009) some HD content might be too heavy to play smoothly. Please try switching to ‘H.264 Pass-through' mode in Beamer’s Playback preferences.
  3. Please review Apple’s support articles on AirPlay troubleshooting and Wi-Fi troubleshooting.
