You might want to try replex from the dvb-tools package
It does the demux and remux internally and inserts the VOBU packets into
the mpeg. I'm not having any sync problems.
So my process is just
replex -tDVD -o dvdmpg $1 &
dvdauthor -o $WORKDIR -f dvdmpg
dvdauthor -o $WORKDIR -T
growisofs -dvd-video -Z /dev/dvd $WORKDIR
rm -r $WORKDIR
It does cause dvdauthor to spit out a bunch of warnings, but it plays
fine on my dvd player. Xine had some audio gaps using version 0.9, but
the version 0.1.0 that just came out makes xine happy as well.
