Yes, the "join"/"splice" point between m2v files causes problems with
some (many?) hardware DVD players. The symptoms vary in severity -
some players have a momentary glitch and proceed, other places stutter
badly, and some stop playing.

That is precisely what needs to be done.
This has been talked about several times on the mailinglists in the
past. Unfortunately with 17000 messages in the archive it is hard
to find the answers to specific questions.
This may be what you're looking for:

Nothing automated exists to create such a script.
It is not hard to create such a script manually though.
Depending on the version of mjpegtools you are using it may be necessary
remove the YUV4MPEG2 header (that's the first line in a Y4M stream:
YUV4MPEG2 W640 H480 F30000:1001 Ip A1:1 C420mpeg2) from all EXCEPT
the first command. I think there is code present in the current
version to do this automatically. Skipping a line is done with a
simple shell function that reads a line into a junk variable that is
ignored. THe script in the posting above shows how this can be done.
Enjoy!
Cheers,
