Ran across this problem today. I have an LG 4082B burner and I recently obtained a box of 10 Packard Bell DVD-R 1-4x blanks. Burned four of them without problems, but when I tried to burn one today, Nero constantly kept on insisting that there was no empty disc in the drive, e.g the drive does not seem to recognize the blanks at all. I updated the firmware to the newest version and tried a couple of other tricks but so far, nothing I've done has helped with the problem. It reads allready burned disks just fine, tried it. And Im going to try with other brand DVD-R's today to see if the problem is in the Packard Bell discs. Any ideas people?
