OpenSUSE OSS 10, install stops between CDs

Hi list, I'm not new to Linux nor to the Suse flavour. Installed it many times without a single real issue but this time... When CD 1 is done and the usual window pops up requesting the successive CD to be inserted I put CD 2 in, hit [OK] and the following error happens: Media: mount failed. Now: - md5sums are OK, - I've changed my CDs several times (they are rw, either Mmore or Maxell), - CDs can be read in other computers, - I've changed the CD drive (which always works fine with first CD). I'm starting to think the problem may be related to the installation program not unmounting CD x/mounting CD x+1. Any clues? Anything I should have tried before contacting the list? <grin> Thanks, -c
