Hi,
you might remember my recent thread, I had problems burning my DVD. Some "unexpected error" showed up during multiplexing (error code: 800413a3 take a look here).
I've now fixed the problem and I thought just in case someone needs some help how to fix this here's what I did:

I loaded the *.mpeg into DVD lab, demultiplexed it (default option in DVDlab) and put the separated video and audio back into DVD Workshop.
It was a lot of work to redo all 99 chapters and update the menus but now it works fine.

Hope that helps
