I'm trying to encode a bizarrely authored DVD to XviD. Both Handbrake and D-Vision process the feature as running 55 min length, while the actual runtime is double that. The feature has 25 chapters, which Handbrake and D-Vision both recognize.

When I play the disc in DVD Player, I noticed that chapter 11 and 21 each indicate that time elapsed on the main title is 0:00 at the beginning of the chapter. Thus, chapters 1-10, 11-20, and 21-25 each seem to be their own title, but oddly enough, read as title 1 of 3.

Title 1: The first half of the film
Title 2: FBI warning
Title 3: Now available on DVD

How do I access the missing chapters on an encoding program and convert the entire feature to XviD?
