What is that Chap 0 doing there? and should I include it on the DVDr?
And is this the reason why only half the chapters menu actually jumps to the right place in the movie?
Those chapters are from the original VTS_01_0.IFO file btw. the one containing the movie on the R2 Gladiator disk.

EDIT!-----------
Ok, I think I've figured out what is happening, but not why!
It seemes the chapter points doesn't go where they're supposed to. They are set at shorter intervals then in the original so that when half the movie is over there's no more chapter points left. Chapter one goes to the start of the movie, the chapter one quarter through goes to half way through, the chapter for half way through the movie goes to the end and, so on.
Then in the chapter menus when you try to go to a chapter over half way through the movie you end up at the end of the movie instead and goes back to the main menu.
But why does this happen? And how do I fix it?
the chapters looks ok in Scenarist except for the inconsistency you can see here: http://www.stratyon.com/stuff/sce.jpg
I followed the new doom9 DVDr guide excactly btw.
