no one is familiar with "imgburn". Have you try any other software? Give Nero trial version a try or other (there are so..oo many).
I've been told you have to go into the options and change which files you want to work with, but I haven't found any option other than different types of image files (.iso, etc). I have version 188.8.131.52 if that matters, dl'd from the imgburn website.
Any info is much appreciated.
