Also, what does "h:\BDMV\STREAM\00305.m2ts" refer to?
That's the mother video from which the clone and sons are made.
Is that a standard video which I can get a copy of somewhere?
Nope.
That presents an obstacle...
The 'mother' is an M2TS. I'll try trimming it '-to 34.076' while
leaving the beginning intact. The problem is that ffmpeg changes the
DTSs and PTSs of the copy.
…How can I trim 00305.m2ts '-to 34.076' without altering the TSs and
other things?
How about a different approach: look for reference videos which also
demonstrate the problems you see with your videos, and which others can
also retrieve or construct.
For instance, this command:
> ffmpeg -f lavfi -i "testsrc" -to 1:00 testpat.m2ts
generates a 60-second video with a test pattern. Anyone with recent
FFmpeg can generate a video like this, though perhaps not identical. If
you use this as your "mother" video, and apply your test method to it,
does ffmpeg demonstrate the same bugs? If yes, then you can include
instructions to generate that video in your bug reports.
