Matshita DVD Drive Decoding



I just purchased a Fujitsu notebook with a DVD drive which happens to be the Matshita UJ-832S. I want to decode it but tried using multiple programs (DVD Region Free, Any DVD, DVD Region Killer)but can’t get it to work. I have read that Matshita drives with model numbers XX-8xxx usually cannot be decoded. Is there any solution to this? Using software? Using firmware?
