When using the apple hdmi output adapter to mirror to the flatscreen tv, the VLC streamer ui is mirrored during selection, and the video is played full screen on the tv when started.
With old controls selected in the settings, the timeline, audiolevel and play controls remain on the ipad.
With new controls selected in the settings, the timeline, audiolevel and playcontrols are shown on the tv, leaving you no way to stop the video, except using the home button, and then force-killing VLC Streamer.
