There has been some discussion about matters like this in the past years, but I coudn't find a solution for me using MakeMKV GUI. Maybe you can give me a hint what I could do, or have overlooked.

There are a lot of old TV series out now on Blu-ray which I already own on DVD. The DVDs weren't a problem at any time. The order of the titles MakeMKV found matched the episodes on the disc in the correct order.
But on Blu-ray with its multiple playlists and other differences, it is no use because the title numbers are random (?) instead of the sequence it would be watched.
The worst case was the Batman 60s series, with its 12 episodes a disc, showing each twice and in random order was kind of horrible to manage afterwards.
Suddenly I have realized that there is a unique segment map number where I could at least uncheck duplicates before going on. This helped, but the main problem remained, because I couldn't find a template variable to name the output files after the segment number, which should, in theory, be the correct order as it would be watched. No guarantee I suppose, but maybe good enough to begin with.
In case there is a playlist "play all", the segment map numbers are in their correct order, like the show UFO for instance has: 0, 1, 2, 3, 7
So why would MakeMKV come up with an initial sorting like this - it starts with 3:
Title: t00
Source file name: 00003.mpls
Segment map: 3
Title: t01
Source file name: 00002.mpls
Segment map: 2
Title: t02
Source file name: 00001.mpls
Segment map: 1
Title: t03
Source file name: 00000.mpls
Segment map: 0
[...]
Title: t06
Source file name: 00007.mpls
Segment map: 7
Title sorting is not a big deal, but if I don't have the "magic number" in the name, I have to look into every episode to see what's in there and rename it.
Thanks in advance!
