I have a NEC DVD_RW ND-3500 drive. Some months back I had flashed an update for it as Nero and other burners had problems with the Sony DVD-R x25 disks. Well after Christmas and many new DVD backups and recorded DVD-RW stuff from TV to R disks I had to get a new pack. Thought I'd try the ASDA own brand 25 pack DVD-R x8. Problem is that everytime I try to burn (although the disks are displaying DVD-R on my system)I keep getting ILLEGAL DISK message and burn aborted. Any one else have problems like this? Do I need to re-flash my drive to an older version or are the disks just crap?
