my xp optg computer does not acknowledge this particular dvd - the aviator - i use software ulead dvd player - both my sony dvd rom DDU 1612 and pioneer 108d dvd writer are unaware of this dvd.this is obviously a deliberate attempt to prevent backingup the dvd - which plays on all standalone dvd’s. any suggestion please - thanks for your patience - engeejay
