My NEC ND 3500-AG (2.18 firmware) won't recognize a certain DVD-R that was probably mastered from a tabletop DVD recorder. I purchased a 3 disc set at a "Collectors Show," the other two are recognized and can be backed up. No matter what program I use; Nero, Roxio DVD Copier, DVD Decrypter
& DVD Info etc. it says the disc is empty (blank media), yet it plays fine on my standalone player with menus. Are there certain settings within the above mentioned
software I should be checking? My drive is set to DMA. I would like to make exact copies on my writer to share with my friends.
I'm not sure it's finalised, how can I tell? Is there anything else I can try or am I just out of luck making backup copies?
Any help would be MUCH appreciated.
