Neither can I..

Apparently it is possible, but that implies that with those discs, the "Ignore CD-ROM serial numbers" option would not have helped you either.
Anyway, one would think that if this option was removed, it should have been replaced by a different volume matching algorithm to prevent these problems. Are you actually seeing that ThumbsPlus is cataloging different discs as one volume, or do you only expect it to do so? Unfortunately I have no suitable CDs at hand to try this with.
