My DENON DN-2000F MKII dual CD player won't read CDs burnt with an ASUS DRW-1608P3S DVD/CD recorder. Neither it reads discs burnt with a similar LiteOn drive. It does, however, read the ones recorded with my former ASUS CRW-5232AS CD recorder and other "CD-only" drives without problems. It seems that it won't play anything burnt by a laser meant both for DVDs and CDs??? Why? Is there any technical explanation???
