I recently tried to burn the NTSC version of Xenoblade Chronicles to an 8.5GB Verbatim DVD-R DL disc using ImgBurn. When I tried to burn the ISO onto the disc, I got some type of error where the program kept trying to do something (it was a while ago, but I think it said it was trying to write a "lead-in") and froze, and I couldn't close out of it, so I had to re-start my computer.
I did some research to see if there was something wrong with my DVD burner, and I downloaded a program called Nero Infotool to see if my drive supports dual-layered discs. The program said that I can use 'em, so I figured I must've done something wrong in ImgBurn. I looked up the error I had in the program, and I read somewhere that in order to burn dual-layered Wii games onto a dual-layered disc you need to manually set a layer-break in the ImgBurn options. So I tried messing around with that, using a value that was said to work with Super Smash Bros. Brawl, and the ISO seemed to have successfully been burned onto the disc. When I popped it into my Wii (which can read dual-layered discs, by the way), however, I got an error message when trying to boot in in Neogamma.
I've successfully burned Wii games onto DVD-Rs before, but none of them were dual-layered. Additionally, the ISO seems to work when I run it on Dolphin, so I don't think the problem is with the game itself. Am I doing something wrong? Is there a specific layer-break number for every dual-layered Wii game? I also plan on burning The Last Story, so any help with either of these games would be appreciated.
