Dolby Digital

Dolby Digital (earlier called AC-3) delivers five discreet full-range channels (left
front, center, right front, left surround and right surround) plus a separate Low
Frequency Effects (LFE) channel.
Many soundtracks on the latest generation laser discs, DVDs and High
Definition Television (HDTV), are encoded with Dolby Digital technology.
When a 5.1 channel Dolby Digital program source is playing, such as from a
game console, Creative PC-DVD player or DVD player, the Dolby Digital
indicator light will illuminate automatically.
Note: Not every section of a DVD will be 5.1-channel encoded. On many
DVDs, only the main movie program will be available in 5.1 channel sound.
Other supporting chapters (like a "Director's Comment" section) may be in
stereo or mono. These sections will not light the Dolby Digital indicator even
though the sound will be properly reproduced by the PS2000 Digital.

Creative Multi Speaker Surround (CMSS)
CMSS is a 2-channel to 5.1-channel sound processor similar in some aspects to
a Dolby Surround Pro Logic processor.
The Music and Movie modes create a virtual 5.1 audio experience.
