May be you can analyse the structure of the DVD using IfoEdit ?

Chapters are a misconception.

DVD consist of Domains, TitleSets, Titles, PGCs, PGs and Cells (top to 
bottom structure).
Chapters are in fact only pointer markings optionally attached to PGs.
The transitions between structural blocks get larger with higher 
structural level.
E.G on PGC level it's almost like starting a new presentation, e.g. audio 
and video needs to be completely restarted.
May be this were the VDR dvd-plugin has it's problems to play some 
structural transitions seemless.

May be you can post a copy of the .IFO files on the questionable disc and 
I can give you some hints or advices 
(I work with DVD software profecionally and have access to all the specs 
and tools neccessary).

kind regards Peter
