Ok, now I've upgraded Firmware of the Pioneer drive to version 1.68. Also upgraded Nero copy program to version 5.5.7.2. I have copied both a DVD Film and a DVD PS2 game. Neither of these two will work in the PS2 but both are recogised by the DVD writer as valid disks. Is this a problem then with the way they are written or by the PS2.
I followed the copy insructions for Nero from
