made up of one Video Manager (VMG) and multiple Video Title Sets (VTS). The VMG is
composed of up to three files:
1. VIDEO_TS.IFO consists of control and playback information for the entire DVD.
Locations of all Video Title Sets on the disc are stored in this file. The first-play
PGC is also stored in this file. VIDEO_TS.IFO is known as VMGI (The Video Manager

is usually designed to get access to video titles present on other VTS, and is
