Common knowledge... always look to MPLS numbers, as title numbers are variable, dependent on what a user sets 'Minimum title length (seconds)' to on the Preferences > Video tab. However, even MPLS sequences can vary depending on retail/rental/regional versions of a release.

What does MakeMKV report for drive info/LibreDrive info (right-hand pane... copy/paste)? If the drive is compliant, it is "so simple".

I believe this discussion (tool) applies only to Pioneer drives, but since you state you have LibreDrive enabled FW, try:

MakeMKV drive speed control

Preferences > Protection tab > Custom Java executable location

1st of all, text in the MakeMKV Info (right) & Output (bottom) panes is selectable & is much easier to copy/paste/quote/review than images (IMO). Each sub-forum offers FAQs/pinned posts addressing most common issues & is the best place to start when encountering an issue. In your case, t...

I'm just looking at this now. Confusing alright. Well it seems like the segment map is exactly the same between the duplicates, so I guess that means it doesn't matter does it? One thing I find strange is the shortest version of movie has most chapters, 23, whereas the others have only 16 chapters?...

In my limited experience, SOCKS5 supports (requires?) authentication, making it incompatible w/ MakeMKV's current proxy implementation, as I see no means of passing credentials. However, that may well be deemed overkill.

Use MakeMKV to rip the parts... all parts of the movie must be from the same source (i.e. multi-disc set), encoded with the same parameters into the same audio/video codecs, so make sure to select the same streams in each part. Use MKVToolnix to join parts... [HowTo]: joining multi-part movies files...
