I can now reproduce the problem which may be fine for you.

Unfortunately, if I'd like to fix it how would I know it 
is fixed? Seriously, you should always upload source files 
and not output files.

In this case, try to cut your input sample (with mkvmerge?) 
to get a small mkv file that allows to reproduce the problem.
