i just tried to replicate this. the only difference was the firmware and the fact that I burned at 12x instead of "max". i normally make my drive settings in qsuite, but i changed them in imgBurn this time to see if that might have been an issue.
I've had no problems with BCHB f/w, but some have. updating to F or G if you don't like H is probably recommended.
i attached my ImgBurn log. disc quality scan on the way...
