Hi New to this usergroup, so forgive me if this is a no BRAINER When trying to back up my files to DVD-RW, it only burns (completes 74 % of the files being copied and then the whole system locks up). I have to manually reboot, nothing works. There is no end to the write attempt, it never completes the selected task. Using Nero Back It Up. OS. Win XP PRO with XP1, Sony U10 A writer. FUJI DVD-RW ... Have not tried other brands of media.
