As you can see in the code above, there are 3 buttons in VMGM PGC 2.

The first button covers the whole screen, so that if you click anywhere in the image, it will be activated. Since the default selected button is forced to 1, it will be also activated in you press the enter button on the remote. His command is LinkTailPGC. So, when it is activated, the post command will be executed, and title 1 will be played.

Button 1 is also set as the default activation button. This has no effect if you leave the still time of the cell to 255 (infinite), since the menu will pause ad infinitum. But if you change the still time duration, button 1 will be automaticaly selected when the delay is over, and title 1 will be played.

The button linked at the right of button 1 is button 2. Button 2 is a verry small, hidden and auto-activating button, with also a LinkTailPGC command. So, if you press the right cursor on the remote, button 2 will be selected and automatically activated, and title 1 will also be played.

The button linked at the left of button 1 is button 3. It's also a little, auto activating button, but this time with a RSM command. So, if you press the left cursor, you will resume at the point where the playback was interrupted.

The Prev, Next and GoUpPGC links are also set in PGC 2, so that, when pressing the previous chapter button when the menu is displayed (PrevPGC Link), the PGC 3 will be executed: a resume is done.

The NextPGC link point to PGC 2 (itself), therefore the post command is executed, and title 1 is played.

GoUpPGC is set to Resume. So, if you press the GoUp (aka Return) button of the remote, the playback will resume.

PGC 1, callable with the Title Menu button of the remote, is used to jump to the next title of the DVDShrink reauthored DVD, via the First-Play PGC. This is the normal usage of the Title button if you apply the DVDShrink Remote Buttons macro. It is not directly related to the menu.

In the guide, I explain how to change the original commands of your DVDShrink reauthored DVD, so that the menu is called before title 1. But that's easy to understand, no?
