My NEC ND 3500-AG (2.18 firmware) won’t recognize a DVD-R that was probably mastered from a tabletop DVD recorder. I purchased this DVD-R at a “Collector Show”. No matter what program I use; Nero, Roxio DVD Copier, DVD Decrypter & DVD Info etc. it says the disc is empty, yet it plays fine on my standalone player with menus. 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.
