I have a 3in1 mkv remux I'm trying to convert back to BD.
I only want one of the versions, not all three, but I will keep all three if that is the best answer.
After an hour of research it seems impossible.

TsMuxerGUI crashed when I tried to load the .mkv, multiAVCHD doesn't recognize the chapters/playlist.

Is xin1-ing a disc a one way process?
