How to safely exclude a PGC during ripping with DVD-Decrypter?

[20/20]

Hi Guys.

I'm rippind this DVD and have a question about the ripping process with DVD-Decrypter.

In the beneath picture, the PGC marked with a red arrow (PGC 15),
Is the part of the video I do not want to demux along with the video.
How do I get about doing this?



I figured maybe "unchecking" the corresponding chapter beneath in the subwindow of that PGC
should do it.
But I don't know if this is safe to do. I thought maybe I could get sync errors or something.

This can also be deleted. Pretty stupid question indeed.
But I'm still a noob.
