Recent discs are split with multiple M2TS.

I am having an issue extracting subtitles from a disc, from a multiple M2TS release. It also seems like this is not the only one recently that has been made like this. This does seem new, so some insight into that is appreciated.
I know I can use the mpls to extract, but this is new in that I cannot access the subtitles unless playing the disc.
American disc, and GBR disc, has the same build. The disc info says it has subtitles, but if you try to extract them, you only get half of them. None of the files have the rest of the subtitles..
My Young Auntie 1981 is the title.

Blu-rays (including UHDs) support seamless branching. As such, it is relatively common for a single title (aka .mpls) to be comprised of multiple .m2ts files.

Are you trying to understand seamless branching or are you asking a different question?

Blu-rays (including UHDs) support seamless branching. As such, it is relatively common for a single title (aka .mpls) to be comprised of multiple .m2ts files.

Are you trying to understand seamless branching or are you asking a different question?

How do I extract subs from these types of discs if mpls does not have subtitles upon loading into programs for demuxing? Strange I'm only seeing the seamless branching now after so many years of watching BD's.

The few times I've needed to extract subtitles, I've always done it from a .mkv file and used the MKVToolNix tools. MakeMKV assembles multiple .m2ts files into a single .mkv file.

There are others on this forum who know a lot more about subtitles than I do. If they choose to comment, they'll probably have better ideas than I do.

I guess I'm dumb. I got it figured out with Makemkv.
