Thanks for the help.

I've got this script working for recording a DV from a MPEG2 stream

cd /cache/tmp

mkfifo aud0
mkfifo vid0
mkfifo dvdmpg
mpeg2desc -a0 < $1 > aud0 &
mpeg2desc -v0 < $1 > vid0 &
mplex -f 8 -V -o dvdmpg aud0 vid0 &
dvdauthor -o $WORKDIR -f dvdmpg
dvdauthor -o $WORKDIR -T

rm aud0
rm vid0
rm dvdmpg

growisofs -dvd-video -Z /dev/dvd $WORKDIR

rm -r $WORKDIR

Presently it works for _just one at a time_ but I do know how to
modify it to put multiple MPEG2 files on one DVD.

What I'm trying to do is create one like it to use .vob files
as input foder.

Thanks for any clues on this. I really don't understnad just how
this whole thing workd.

I'll go read the references you pointed to.

Thanks again.
