quality. DivX uses lossy MPEG-4 Part 2 compression, where quality is balanced against
file size for utility.

A.1.5 DVD .ISO
An ISO image (.iso) is an informal term for a disk image of an ISO 9660 file system. Most
CD/DVD authoring utilities can deal with ISO images: Producing them either by copying
the data from existing media or generating new ones from existing files, or using them to
create a copy on physical media.
A.1.6 DVD .VOB and .IFO
A VOB file (DVD-Video Object) is a file type contained in DVD-Video media. It contains
the actual Video, Audio, Subtitle and Menu contents in stream form. VOB files are
encoded very much like standard MPEG-2 files. When the extension is renamed
from .vob to .MPG or .MPEG the file is still readable and continues to hold all information,
although most players supporting MPEG-2 don't support subtitle tracks.
IFO file is a DVD information file that stores information about chapters, subtitles and
audio tracks. IFO files contain the formatting information of the VOB files, which tells the
DVD player how the DVD should be played.
A.1.7 .TS
Transport stream (TS) is used in MPEG-1, MPEG-2, and MPEG-4 systems protocols.
TS has features for error correction for transportation over imperfect media, and are used
in broadcast applications. The MPEG-2 transport stream is defined in the ISO/IEC
standard (13818-1).
