just bought this dual layer dvd writer and was using dvd shrink to copy my dvds. ive been using ridata and imation dvd media -r type with no problems and backed up both the bourne supremecy and amityville horror dvd’s. today i bought some ritek inkjet fullsurface printable -r 8x speed dvd media, which doesnt seem to work with the drive. ive tried backing up the punisher (has copy protection) and children of the corn (no copy protection) and both have come out coasters. tried them in the dvd player, doesnt play. please could someone help me out.
