Thank you for your Super Software.
I use them since a long time for my Amazon Fire TV box -> Kodi.
Now I in for the Atmos sound on the Nvidia Shild TV box and unfortunately I have found that the 3D movies I play with the software BD3D2MK3D than 2D.
So all movies run properly as 3D
My 3D movies that I converted with the software BD3D2MK3D
What should I change the settings so that a 3D mkv is created?
Can I save my "old" 3D movies somehow and change the header MKVs something with MKVExtractGUI2?
Thanks for your help
