Thanks.
Since I have seen so far only A and B plus numbers 1 or 2 I couldn't figure out the meaning of this naming convention.
So nothing to worry about.

I don't like DVD menus.
I just extract music dvd main parts into mkv files from without DVD extras.
Then I rename mkv by artist + DVD name and ...

When ripping my music DVD to mkv files result is somehow confusing.
It feels like this naming convention is a message to me which I don't understand.

A1_t00.mkv
A1_t01.mkv
A1_t02.mkv
A1_t03.mkv

or other disk

B1_t00.mkv
B1_t01.mkv
B1_t02.mkv

I believe there has also been mixed results from same ...

MakeMkvBeta 1.17.3 win x64 release.
Saved MKV files start with A or B followed by number.
Probably some indication of source properties?

Does anyone know why file names are starting with A or B, sometimes followed by number 1 or2?
Something to acknowledge about?
I have been searching answer for hours already but no luck.
Thanks
