add extra chapters w/out messing chapter menu?

[sadsack]

On some dvds, I like to add more chapter breaks by splitting cells using Vobblanker (I don't know how to do it in Pgcedit).
However this messes up the Chapter Selection Menu (the thumbnails won't correspond with original chapters anymore) (with the exception of adding chapters AFTER all the current ones).
Any way to add extra chapters so they aren't utilized by that menu?

I should have mentioned I prefer the freeware solutions.

No, you need to redo the navigation as warned in the application. Use PgcEdit to edit the menu buttons.

is there a guide for this?

[blutach]

Not that I know of, but all you need to do is examine the PGC in PgcEdit (http://www.videohelp.com/~r0lZ/pgcedit/index.html) and determine which new chapters the old chapters now correspond to.

Then go into your chapter menu and edit the menu buttons - typically, if the menu is in the same VTS as the movie, you will change your commands to the correct JumpVTS_PTT - eg Jump to Title 1, Chapter xx. You will need to do this for all buttons in the chapter menu past the insertion points.

If other programs are of interest as well, then you can do it quite easily with DvdReMake Pro: http://www.dimadsoft.com/dvdremakepro/ht_insert_chapter.php

Of course - we should have mentioned that! The prorams and chapters are adjusted automatically :)

Thanks, blutach!

also, if you don't add chapters, only programs when splitting, it will behave as a chapter stop when using next/prev buttons, still, chapter numbers (and correspondig buttons of course) stay intact

I agree, although I'm not sure that doing so is legal. I've read somewhere that in a sequential title, the chapter numbers must match the program numbers. However, like you, I add often some programs without chapters, so far without problem.

@Robotik

Many players use Next/Prev as Next/Prev Chapter - r0lZ devised a test to see what your player did - it is on his website, I think.

oops, i never knew that, thanks. i've used this method frequently

[r0lZ]

The test DVD (available in the Download section of my homepage) checks what the player stores in SPRM 7. It's normally the chapter number, but many players store the PG number instead.
The fact that they go to the prev or next PG or chapter when the prev or next button is pressed might be related to the SPRM 7, but I haven't verified that.

According to the Philips verifier every program must have a corresponding ptt. According to DVD Demystified 2nd ed p269 footnote "Specifically every chapter is a program, but not every program is a chapter". Also on p269 "The 'Previous' and 'Next' buttons on the remote control jump between programs..." This book also lists SPRM 7 as holding the pttn, ie chapter number.

Just one of those confusing areas either not well thought out at the time of writing the spec, or poorly translated from Japanese.

Another good one is why the VMG menu is called "title" and the VTSM has a "root" menu. true the VMG menu chooses a title, but what does root mean? to those with even a passing knowledge of operating systems, root is the top-most node in a file system.

Thanks for the confirmation... that the PG/PTT definitions are confusing!

I remember I've read that the PGs are like sub-chapters. According to the author, the players are supposed to have two sets of Prev/Next buttons. One to skip to the next program, and one for the PTTs. However, as they are already many buttons on a DVD remote, the industry has never really implemented this idea, and now, PG and PTT are almost synonyms.
Can it be true?

Unfortunately, I can't remember where I've read that, as it was before I begun to write PgcEdit. However, I can confirm that something similar exists for the CD-audio. My first CD player had 2 sets of prev/next buttons. One was used to skip to the next track, and the other to skip, for example, to the next movement of a symphony.

those who create specs should come here first to ask people's opinion. and that goes to politics, too. every decision that is done by some and affects many should be discussed before taking effect.
are hd/br specs also a mess?

According to the Philips verifier every program must have a corresponding ptt

This is applying to "one_sequential_titles" only...as well SPRM7 is valid for one_sequential_titles only

One was used to skip to the next track, and the other to skip, for example, to the next movement of a symphony.

Of course, as the PG and PTT numbers must be different in a non sequential title (except in the entry PGC.)
The question is: Is it legal to have PGs without corresponding PTTs in a one_sequential title?

Right, I did not remember the word "index".

As far as I can judge with my software and hardware DVD players, a PG is like an index, and can be used to skip somewhere inside a chapter with the remote. We know that the fact that the philips verifier complains doesn't mean that it's really illegal!
