Changing the Sound

When playing a DVD VIDEO recorded in
multiple audio formats (PCM, Dolby Digital,
or DTS), you can change the audio format. If
the DVD VIDEO is recorded with
multilingual tracks, you can also change the
language.
With CDs, DATA CDs, or VIDEO CDs, you
can select the sound from either the right or
left channel and listen to the sound of the
selected channel through both the right and
left speakers. For example, when playing a
disc containing a song with the vocals on the
right channel and the instruments on the left
channel, you can hear the instruments from
both speakers by selecting the left channel.
