Following up with an answer to my own question, the necessary
information is embedded in the original .nuv file and can be extracted
with mpeg2desc.  The mplex line in the DVD creation instructions needs
to be changed to something like:

    mplex -f 8 -O `mpeg2desc -m $1`mpt -V -o dvdmpg aud0 vid0 &

I hope this helps someone else.
