Hi Megalith
Muxing Multi-Edition BDs with mkvmerge don't work really well. The issue are the
identical frames and maybe the audio-gaps also.
For such BDs I use eac3to to demux the audios. Like tebasuna51 wrote:
You could test a demux with the parameter "-no2ndpass".
My chapterEditor is special designed to preserve both(or more) editions of the movie in one mkv and eac3to is used to fix such issues.
