  • A copy of the VTSI ( VTSI Backup).

A DVD can hold up to 99 titles (VTS), each divided to 10 chapters.
The VIDEO_TS folder usually contains three types of files, with the following extensions:
  • IFO containing navigation information.
  • VOB (Video Object Block) containing the video stream, the audio channels and subtitles of a video title .
  • BUP (BUP - Backup file) containing a backup of IFO files.

The file named as VIDEO_TS.IFO (IFO - information) contains the necessary information for the DVD player to display the main menu. It is accompanied by VIDEO_TS.VOB file containing the introduction animation, as well as a backup file (named as VIDEO_TS.BUP).
