from a DVD-Video soundtrack.
Movie 6 A decoded multi-channel Cinema
DVD-Video soundtrack.
You can change any of these presets using the Store key; for
more information see Changing the DSP preset for a source,

Multi-channel presets
The 568.2 is provided with two alternative multi-channel presets:
Discrete and Cinema. Discrete is intended for use with music
material. Cinema is a user preset based on Discrete but with
settings more appropriate for movie material.
Subwoofer configuration
The intelligent stream content information provided by the MHR
Smart Link also allows the 568.2 to choose an appropriate
subwoofer configuration depending on the stream content: the
Music layout for Music 2 and Music 6 DSP presets, and the 5.1
Movie layout for Movie 2 and Movie 6 DSP presets.

The 568.2 Digital Surround Processor supports Meridian High
Resolution (MHR), to allow you to connect to other MHR-
compliant Meridian products to take advantage of high-rate
audio sources, and provide the additional benefits of lower jitter
and improved sound quality on all sources.
