Next DVD audio track

Copy this to ~/Library/Application Support/DVD Player Scripts/12 Next Language.scpt

When called, the script will cycle one step through the available audio tracks, e.g. the next audio track.
Since apples DVD Player lacks a “choose audio track” menu, this does the trick.

OS version: OS X

tell application "DVD Player"
	set audioTrackMax to available audio tracks
	set currentAudioTrack to audio track + 1
	if currentAudioTrack > audioTrackMax then
		set currentAudioTrack to 1
	end if
	set audio track to currentAudioTrack
end tell
