What are Title/Chapter and Track?
Title/Chapter (DVD)
DVDs are divided up into large sections, titles, and smaller sections, chapters. The numbers allocated to
these sections are called title numbers and chapter numbers.
DVD
Track (VCD/CD)
Video CDs and CDs are divided up into sections called tracks, and the numbers allocated to these sections
are called track numbers.

What is MPEG-4?
MPEG-4 is a video compression standard developed by an industrial group called 'Moving Picture Experts
Group' or 'MPEG' for short.
MPEG-4's official description by the MPEG is 'a standard for Very Low Bitrate
Audio-Visual Coding'. Many of the standards developed by this group are accepted standards by the ISO
(International Standards Organization) and are therefore also called ISO-standards. MPEG-4 is ISO/IEC
standard #14496.
The MPEG standards are widely accepted by the media industry and you can find them in
VCD's, DVD's, mp3's and all sorts of other applications.
To compress a high quality 2 hour video clip to something that can fit on a single CD obviously takes some
serious compression tactics. MPEG-4 does this partly by removing information that we don't notice and partly
by transforming the raw pixel data into a mathematical approximation of that data. The approximation is close
enough for us mere humans not to notice the difference between the source and the result (well, at least in
theory).
What are XViD, DiVX?
Both of them are video codec (encoder/decoder) base on MPEG-4. Each of them can encode a video-file into
a (hopefully) MPEG-4 compliant data stream which can be saved into a container-file like an .avi, .ogm, .mp4
or others. The unit has a built-in MPEG-4 decoder, with it you can play XViD and DiVX video disc.
