I THINK it checks the total data per byte, including both the data byte and the correctional margin, to see if there is correctable failure of individual bits.

Did your "marginal burns" include both CDs and DVDs?

Because I've only seen full-speed Yellow run-overs on damaged CDs - dodgy DVDs just tend to straight to Red.

If you have marginal CD burns, you might check them now.

As for the screenshots I posted, I have had other CDs like this but like I said, I binned them after the scan.
