from man dvdauthor...
dvdauthor - assembles multiple mpeg program streams into a suitable DVD
       filesystem

OK here is a v. basic dvd.xml...

<dvdauthor>
  <vmgm />
  <titleset>
   <titles>
    <pgc>
     <vob file="movie1.mpg
"chapters="0,0:30,1:00,1:30,2:30,3:00,3:30,4:00" />
    </pgc>
   </titles>
  </titleset>
 </dvdauthor>

you can find better examples with menus, splash screens etc on the web.

the previous script creates the dvd file system in the 'output'
directory from this line using a supplied xml file...

echo "Authoring DVD..."
        >>dvdauthor -o output -x dvd.xml

To write back to single layer dvd I use...
growisofs -Z /dev/dvd -dvd-video output/

HTH
