of these connections are for running the Digital soundtrack
of the movie into a Digital amplifier or decoder for Digital
Surround Sound. If only a short run is required from the DVD
to the amp, we'd recommend using coaxial. If a longer cable
is required (up to 10m) we'd suggest using optical as it is
clearly better over very long distances. All sound information
(including ordinary stereo and Pro-Logic sound) will be passed
down these cables. See also: Coax versus optical digital debate.
- Almost every DVD player has a digital audio output.

optical interconnect to the AV receiver/decoder

and PCM) can be one of the following:
