Put 'mkvpropedit.exe' and 'Go.bat' in same file as the .mkv files and run it.
This will remove the embedded text. Then it will show what the filename says instead...

I want to take an MKV file and edit it. Perhaps add a couple of chapters and edit it. Ideally retain the subtitles too.
Is there a program I can use free or purchase?
No idea what...

Couple I've tried, the encoding streams rubbish, size changes etc...

Thanks in advance...
