Hello,

This is not big problem. Also Dan have told that it is fixed in MLT now.
I had solved this problem so: just open this DV in Kino and export as dual
pass VOB :)

But, there is huge problem -> http://www.kdenlive.org/mantis/view.php?id=438

To reproduce:
Open any project, export project as MPEG2, create dvdauthor XML for simple
DVD disk, try to authorize with dvdauthor -x your_XML and you will get
segmentation fault of dvdauthor in 80% cases, the rest cases you will get
non seekable DVD with frozen 10 seconds at beginning of every title.
