I was under the impression if you had the latest version of XBC that it made ixtreme compatible backups?!
Mind you I'm not an expert when it comes to XBC. I prefer to use Schtrom for my backups, I've never had a problem making ixtreme compatible backups with it. Maybe try it out and see if you get the same result, providing you don't mind possibly making another dud disc..........tez
