I have a Magnavox DVR630R and it won’t read discs it recorded earlier (some months, some a year or two). I think that at least some of them are discs that were not finalized. It thinks there is nothing on the disc. I have tried everything I can think of and then some. Does anyone have any suggestions? I have even tried Decrypter to Close but that doesn’t work. Some time ago (6 - 9 months) I installed a firmware upgrade. It may have changed something so I cannot read discs that were recorded prior to that. I just don’t know. I have gone through many of my discs and 1/2 to 2/3 don’t work. A lot of money and time invested that I hope is not lost.
Please help if you can.
