set the enabledTracks of player "Arctic" to 3 & return & 2
Use the enabledTracks property to control the user's ability to play a QuickTime movie.
Value:
The enabledTracks is a list of tracks, one per line. Each track is a track ID (a positive integer).
Comments:
A movie can contain multiple tracks intended to be played at the same time (for example, an audio and a video track), or tracks that are separate (for example, an alternative audio track). You can list the tracks in a movie using the tracks property.
