As the subject says, it just won't read any black surfaced CD-R's. I've got at least 3 different brands, and have burned these on 2 different writers. One brand was part of a multipack with 4 other colours and every other colour plays fine. They play in every other CD/DVD player I've tried. Are all DV88's the same, or do I have a faulty machine? Any help greatfully appreciated.
