Nero 5.9.9.17 works fine for me with DVD-r's (Datasafe, Datawrite and All4Mats (Ritek) disks. Haven't tried any +R disks, theyr'e usually more expensive anyway. Nero has crashed a couple of times right at the end of the disk write (leadout) and locked the drive. Restarting the machine solves the drive lock and the resulting disks have both worked to! Guess I'm lucky, I tried ten disks of Ritek's, Datasafe, Datawrite and Mirror (vivistar). The deep purple ritek's are best but only write at 1x, the Datasafe (Manufacturer ID: TDKG02000000) and Datawrite (work at 2x Datasafe seem more compatible with other players than Datawrite although I can't see any obvious diference. The Mirror (vivistar) seem crap and unreliable so I won't be getting them again. :devil:
