I have an NEC 2500A with BIOS 1.08, when I write using CloneDVD or Nero on a new spindle of Datawrite Titanium ‘Full Face’ Printable (8x) DVD-R every one is a coaster. The writing all seems to go well and ends as expected but then nothing will read the written discs. No internal DVD reader or home Denon 1720 DVD will recognise them. I have noticed that they do seem to show some nasty long scratches on the disc. I’m not putting anything on the printable side, its left blank. I have tried again with my old media of choice, Infiniti, and everything works as it always has previously, fine 100%. I have tried writing the Datawrite with various speeds 2x 4x 8x but theres no difference.
Please, has anyone got any ideas?
