I'm really new to this authoring and trying to create menus for Vob. I used DVDstyler and carefully followed the guide. Used the preview. However, I get this:

Please contact the application's support team for more information.
Error executing of command: dvdauthor -o "C:\Documents and Settings\saigonport\dvd\dvd" -x "C:\Documents and Settings\saigonport\dvd\dvd\dvdauthor.xml"

the vob files are on an external HHD. Where did I go wrong. Should the vob files be in a folder alone in the directory
