Concatenating from ffmpegclipfiles.txt:
ffconcat version 1.0
file 00000.MTS
file '00046 - Copy.MTS'
produces:

The errors start appearing as soon as the boundary between clips is reached.
Clip ordering does not change the behaviour; it recurs at the new clip
boundary.
Individually the clips encode fine.
Concatenating Lagarith-encoded AVI versions of the input clips works fine.
An older version of ffmpeg concatenates the same M2TS files as above to FFV1
without problems:

Apart from absence of error messages, note the higher (and correct) frame
count.
Id be happy to upload the two M2TS input clips if need be.
