Setting the audio format
You can only set the audio format in audio DVD mode. The number of audio formats available depends on the DVD. The content of an audio DVD is called an "album", and this can be divided into up to nine groups. A group can contain music in different sound qualities (stereo and multichannel formats, for example), or bonus tracks. Each group can contain up to 99 tracks. If an audio DVD only contains one audio format, the "Group" menu item(s) cannot be selected.
Switch on audio DVD mode.
Select DVD-A by sliding 
and turning
the COMAND controller and press
to confirm.
Select Group by turning
and press
to confirm.
The list of available groups appears. The
dot indicates the group currently
selected.
To exit the menu: slide 
the
COMAND
controller or press the 
button.
