From 5ea39fc96beb4f56198cfb975a6a37bbd61d10ed Mon Sep 17 00:00:00 2001

Subject: [PATCH] Added support for "VOB lists" (files containing <vob>
 elements to be inserted into the dvdauthor XML file directly). Added early
 test of VOB/list file existence, since dvdauthor doesn't test any files until
 it has processed the previous ones and this may take a long time.
