21. Endless Previous Chapter Skipping

There might be some of you that would like to jump from your first Title to your Last Title.

Or if even you have just one Title.

It's easy to do since you'll be doing to Title 1 the same steps like your other Titles but with some extras steps. 

But first, I want you to repeat Pages 1 and 2 (Steps 1 to 7) with VTST 1.  We need to add a new dummy PGC to VTST 1 and also change your Title's Previous PGCN value.

22. Let's start changing our dummy PGC 2 , Pre commands first.

a. Highlight the hex value templates below that pertain to your DVD.  We are going to a copy and paste.

For re-authored DVD Shrink files with Multiple Titles:

For single Titles:

b. Ctrl+C to copy it your clipboard. 

c. Now, go to your NOP command in your dummy PGC and highlighted it with single left click.

d. Ctrl+V to paste.

If you had multiple Titles, your Pre commands will be this

If you had a single Title, you will have this.  At this point, jump to Step 24.

23. (This Step for Multiple Titles Only)

We only need to edit Pre command #2 of your dummy PGC 2.

a. Double-click on Pre command #2.  We need to change our gprm (0)'s value.

b.  Here's the formula to get your new value for gprm(0). Take your last VTST # and minus it by 1.

E.g. My example's last VTST is 3.

c. Enter your new value.

d. Click on OK to set and exit Command Editor.

24. Now let's move on to our last PGC 1, .  If you only have a single Title, then work on . 

a. Highlight the hex value templates below that pertains to your DVD.  We're going to do another copy and paste.

For re-authored DVD Shrink files with Multiple Titles:

For single Titles:

b. Ctrl+C to copy it your clipboard. 

c. Now, go to your first Pre command in your PGC 1 and highlighted it with single left click.

d. Ctrl+V to paste.

If you had multiple Titles, your Pre commands will be this

If you had a single Title, you will have this.

25. This step is for both multiple and single Titles.

We will be editing Pre command #4 if you have multiple Title

 or Pre command #3 if you have a single Title.  Notice they are the same command?

a. Double-click on your Pre command in question.  We need to change our LinkPTT value.

b. Enter your chapter number

If you have multiple Titles, enter your Last Title's last chapter.  If you need any help on this matter, go to Page 5.

If you have a single Title, enter your last chapter.

c. Click on OK to set and exit Command Editor.

26. Click on to save your DVD.

27. Preview to test your Previous chapter button.

Note: I have tested my backup with a JVC player, and I had to my previous button twice to skip to my previous Title.  My Sony player works with single presses. Don't know why it's like that but I just want to you to know this guide didn't do it that way. ;)

That's it!
