I am trying to merge a DVD that has been split into 2 separate discs. The discs only contain the main movie (and 3 audio streams) and not any menus. I have tried to simply append the second disc, and then proceeded to create chapters pointing to the new programs. The second disc's chapters begin at 25. After exporting a test DVD I run into a problem at chapter 10. I was skipping through the film chapter by chapter when I realized I could not skip past 10, it would just send me back to the beginning of 10 in a loop. Then when trying to get past it by just normally playing it, a few second into chapter 10 the movie begins to jump to different locations.

I've checked the titles to make sure they all point to the right place, but cannot figure it out.

The same thing happens when I add and connect the second disc as a new PGC.

Help is appreciated. Thank you.
