Maybe it's cause you burned it on a mac. Is it a possibility to get a friend with a PC to download and burn it?
I just called him to help
And yeah, what dwhitley said is a good point... my drive has already been unlocked and reordered and all that. I obviously am not going to lock a drive to test this theory, but it might need to unlock each file individually to overwrite it. Maybe it's not a problem with the disc, but the file system. I guess just keep hammering on Retry and see if the number starts going up?
