Well, consulting cdrinfo was your first mistake...

Here is some reading material:http://www.cdrlabs.com/phpBB/viewtopic. ... 9056#59056
One should not only
be concerned with C2 errors, but they are more of a concern since they represent a more serious error, and, in a CD-DA disc, errors can be audible if not corrected at the C2 level. C1 errors are never audible directly, since the C2 layer gets a chance to correct anything the C1 level could not.

Such features typically apply only to ISO 9660 data discs. And even that type of testing doesn't tell the whole picture if you are concerned about the lower-level burn quality, because many low-level problems can be corrected by the three levels of error correction on a data disc. Why should you be concerned about the lower-level burn quality if the error correction successfully corrects all the errors? Because the more work the error correction has to do to correct the errors of the freshly burned disc, the less margin there is to correct additional errors that may show up as the disc ages and becomes scratched.
