I need help getting Ctrl-B (next chapter) to work!

You are not only a "BSPlayer Master", to me, you are a "Hero of BSplayer Universe".
The conversation with you taught me a lot undocumented facts about this versatile program and was important help!
Thank you very much!

I hope that Ico-Man reads our conversation. He may freely use my findings summaries screenshots for a future F1 Help or a future User's Guide).

Again, refering #5:

How about a small part from this file? Just a chunck with 2 or 3 chapters. Would be interesting to analyze the embedding. Could you please upload a sample chunck from this file? (refering #11, #13)
PLEASE!

Edit:
P.S.
Just tested extracting embedded chapters from mediafile.mkv
using Chapters Extraction with MKVExtractGUI2
MKVExtractGUI-2 | Free software downloads at SourceForge.net
1. Drop media_file into Input File.
2. Tag Chapters.
3. Select Chapters format: ogm -> get media_file.ogm
4. Select Chapters format: xml -> get media_file.xml

results for your sample2.mkv (after copy/paste into a notepad text file):

(xml file looks better, i.e. structured, in an internet browser)

Instead of uploading a chunck from the file refring in #5, #11, #13 you may prefer to let MKVExtractGUI2
extract the ogm and xml versions of the embedded chapters and append the *.ogm und *.xml files?
