dvdauthor - skok z menu na kapitolu

[Ludek Bartek]

Dobry den,
nevite prosim Vas nekdo, jak se v DVDauthoru z menu dostat na kapitolu v 
nejakem titulu?
Podle manualu by melo stacit:
<dvdauthor>
<vmgm>
 <menus>
  <pgc>
  ...
  <button name="1">jump title 1 chapter 1;</button>
   ...
  </pgc>
 </menus>
</vmgm>
<titleset>
  <titles>
    <pgc>
     <vob file="..."/>
     ...
    </pgc>
  </titles>
 </titleset>
</dvdauthor>

ale kdyz to zkusim pouzit, tak se dozvim:

ERR:  That form of jumping is not allowed
ERR:  in VMGM pgc 1, button 1

Mockrat dik za libovolne nakopnuti i smerem k rozumne literature. 
Bohuzel ani Google ani primo dvdauthor.sf.net mi nepomohli.
