the standard surround channels. This additional channel provides the
opportunity for more detailed imaging behind the listener and brings
more depth, spaciousness and sound localization than with standard
5.1 surround encoding.
THX Music
For playback of multi-channel music, the THX Music Mode can be used.

Video Source Surround Modes
The following modes are available for multi-channel digital sources.
Special modes such as DTS ES and DTS 6.1 Discrete are only available
from properly encoded source materials.
Dolby Digital 5.1
This is the most commonly used surround format for DVD, Digital
Satellite and Broadcast television. Dolby Digital 5.1 delivers surround
sound with five discrete full-range channels and a low frequency bass
effects (LFE) subwoofer channel.
DTS 5.1
The DTS 5.1 mix is less common that the Dolby Digital format, although
it is generally acknowledged to having superior sound quality. It has the
same five full range channels plus the subwoofer channel.
DTS-ES
DTS ES is a 5.1 channel format based on DTS 5.1. There is an additional
center rear channel that is matrix encoded into the rear surround
channels for playback.
DTS-ES 6.1 Discrete
This is a true discrete 6.1 channel sound format. Unlike DTS ES, this
format has a true sixth channel mixed into the soundtracks. The DTS
6.1 Discrete mode only operates on sources with DTS 6.1 encoding. A
list of available DVD titles with DTS ES and 6.1 Discrete can be found at
