What is Cell-id ?

[Satirik]

On my dvds sometimes there is as cellid as chapter sometimes there is one cell-id more than chapter ? what is the diference between the both

A DVD movie is splited in several "cells".
Sometimes you have 1 cell per chapter, sometimes you have several cells per chapter.

Imagine you want to choose the end of your film.
You have one cell per chapter except for the "end" chapter.
The "end" chapter is splited in 2 cells.
The DVD will have 2 ProGram Chains (PGC).
Cell will be linked in 2 different ways :

Happy end : 1 -> 2 -> ... -> 18 -> 19 -> 21
Bad end : 1 -> 2 -> ... -> 18 -> 20 -> 21


If you have more than 1 cell per chapter it's that you want to be able to access the movie directly in the middle of the chapter.

I hope it's clear :o
