Last weekend I compiled a new executable from the git. This included John's "put tsfix before the global headers. fixes problems where recordings .." fix.
Suddenly, I sometimes see Chapters in the mkv files.

Before:

Not always, but before last weekend I never noticed Chapters. I notice because when I send an mkv with 2 Chapters to my Samsung D5700 via Serviio, it tells me the format is incorrect (no play).

Could the switch of the global headers have "fixed" something where Chapters are now suddenly in some of the recordings where previously they were missed?
