Hello. First edit out your serial#...it begins with 1A20.Quote:Nero Version: 6.6.0.16Update Nero, current version is 6.6.0.18Quote: Bus Type : default (0) -> ATAPI, detected: ?Your PC is not recognizing your burner. The solution could be fixed in the next suggestion.Quote:CdRomPeripheral : AOPEN DVD1648/AAP PRO nvatabus Port 0 ID 0 DMA: OffCdRomPeripheral : PHILIPS PBDV1640P nvatabus Port 0 ID 1 DMA: Off DMA need to be enabled on all drives. You can change this through your device manager.Quote: Disc Manufacturer ID: CMC MAGCMags are some of the worst discs you can use. Just search the site and you find hundreds of complaints about this media.Quote: Disc finalized, LBA total Image size: 3587678 (7007MB), Last LBA L0: 1793839 (3503MB) Since I have not tried a DL burn I would assume that the disc only burned to the layer break.Quote:Existing drivers:File 'Drivers\InCDfs.SYS': Ver=4, 3, 20, 1, size=101504 bytes, created 25/07/2005 11:53:28 (InCD4 driver for win NT/2K/XP)File 'Drivers\InCDpass.SYS': Ver=4, 3, 20, 1, size=29696 bytes, created 25/07/2005 11:53:04 (InCD4 driver for win NT/2K/XP)File 'Drivers\InCDrec.SYS': Ver=4, 3, 20, 1, size=8704 bytes, created 25/07/2005 11:53:30 (InCD4 driver for win NT/2K/XP) The INCD packet included with Nero is notorious for alot of problems. You need to uninstall Nero and reinstall, leaving out the INCD packet.These are a few things I picked up and should get you going again, but I'm sure others will be by with more tweaks.Also why not just use DVD Decrypter in ISO->read mode and then burn in ISO->write mode with the MDS file? It is supposed to do a much better job at DL backups than most other programs.
