I want to burn my Wii Sports backup to one of those printable DVD but I'm having a hard time copying the backup I made to DVD-R. I can't find my original at the moment but RAWdump that I used for the original doesn't seem to work for a backup.
IIRC you don't need to use RAWdump on a backup. You should be able to just use "read" mode on imgburn to make an iso, then reburn the image with "write" mode.
