DVD File Structure & Formats

Folks:


Whenever I look at a DVD, I always notice the following structure:

First there are 2 folders: AUDIO_TS and VIDEO_TS
AUDIO_TS is always empty
VIDEO_TS contains the following file formats: VOB, IFO, etc

* Can anyone explain to me why this particular structure ?
* What is the purpose of the various file formats: VOB, IFO, etc ? I
know VOB is for the actual content. I use Real Player
* Can any of formats be used for security (anti-copying) purposes ?


Appreciate any explanations plus references that would allow me to get
additional information.



Thanks,
Jo.
