Alright, I have downloaded the official MacOSXLeopard.dmg to install Leopard onto my computer. Now, when I try to burn it to a DVD+R DL using Disk-Utility or Toast Titanium, about 70% through the burning suddenly stops and gives me an error message and I'm left with a DVD+R DL disc that can't be used anymore. I have wasted 3 discs already trying to burn it other ways, but all the ways have given me the same results. I think I might have the format of how to burn it incorrectly set.
HELP PLEASE!
