Multiple symptoms:
* Verify of CDBurnerXP warned that verify failed in both attempts.
* Copying one of the CDs burned with CDBurnerXP to hard disk failed.
* Booting another computer from the CD (an openSUSE installation image)
worked, but the inbuilt "check installation medium" (or whatever it's
called) ran on a CRC error in one case, and some other error in another
case.

Ran an md5 check on the image, and it was ok. Being an official openSUSE
11.2 installer image, I guess Jim will confirm that we can rule out bad
mastering :-)

Hm, now that you mention it... I'm not sure, I /might/ have kept them
for a while where they'd get a beam of direct sunlight for a few minutes
on a sunny day. Not sure though.

They're still in the original cakebox; you'd expect that to be somehow
suitable for storage of CD-Rs ;-)
