Version 2.0 VCDs/S-VCDs have Playback Control

20.2 What are Title and Chapter?
Title is the name given to the largest units of image
and sound units on DVDs; on many DVDs the (Main)
film has the title number 01. For bonus material (i.e.
Film trailer, background information etc.), that is
available on many DVDs, other possible title numbers
can be used.
Chapter is the name given to the next smaller image
and sound units beneath title. If the DVD/VCD/S-VCD
or its title is divided into chapters, numbers are assigned
to you, through the input of which the chapter can
be selected direct.
Bear in mind that not on all DVDs …
• are the DVD or the title divided into (numbered)
chapters
• Chapters are also designated as "Scenes" (i.e. in
the main menu of DVDs)
20.3 Dolby Surround
Dolby Surround is an analogue sound format, by
which the two channels of a stereo sound signal are
used in order to accommodate room sound information
for further channels. With a Dolby Surround decoder
the signals are again converted into sound and/or
music and are fed to two additional loudspeakers,
which are to be situated behind the listening area.
Dolby Prologic
In comparison to Dolby Surround sound format, with
Dolby Prologic an additional channel in the stereo
signal is used; this is the so called "Centre" channel.
The corresponding centre loudspeaker is to be situated
in the middle between the stereo loudspeakers.
The deepest sounds are fed to a bass loudspeaker,
the so called "Subwoofer". The subwoofer can be
placed in any desired location in the room; the logic
for this is that the bass sounds that the subwoofer
puts out can scarcely be localized exactely by the
human ear

for three front and two rear surround sound channels,
the "1" for the bass sound chanel.
DTS
DTS is the abbreviation for "Digital Theatre System"
and refers to one of the most common surround
