I wonder why we wasted so much time on that, sorry to everyone!
It happens, but as long as you having it working now that's the important thing.
Using XP SP2 I downloaded ImgBurn 18.104.22.168 ( http://www.imgburn.com
) and the .iso linked in Daniel Ferreira's post #7, followed the instructions there and it worked as expected. Haven't checked MD5, tried booting the disc or running gparted but the burning part was simple enough.
