Ok, so now i've got a full backup of a 3D-blurays.
It is not an ISO but a backup just as it is created by makemkv.
How should i proceed if i wanted to rip just the main title with some additional language audio and subtitles from that backup?
I thought i simply could load that backup into makemkv and then edit the movie just as i would do do with a physical BluRay disk that is loaded into makemkv.
But unless i miss something there is no way to load the backup into makemkv.

Any hint is very much appreciated

You have to select "Open files manually" and then select the index.bdmv file inside of the bdmv folder

Many thanx,
i don't know if it ever would have occurred to me to try something like the index.bdmv file
