MMC standard requires, that a drive should not reveal a title key on a region mismatched CSS protected disc. (It should return "Illegal request - region code does not match"). Some drives are even less restrictive and even give you the title key on region mismatch. But AnyDVD can usually reveal the title key with a brute force attack, as long as the drive allows you to read the scrambled sectors. Matsushita (Panasonic) drives do not! You CANNOT read the scrambled data, if the region code doesn't match. No other drive behaves this way, only Matsushita (Panasonic) drives do, as the standard does not require a drive to not reveal the protected data on region mismatch, but Matsushita (Panasonic) drives are more restrictive as they need to be.

There is nothing AnyDVD, DVDDecrypter, or any other software can do about this. Sorry.

Solution: Set the drive to a region, and only use matching discs. AnyDVD will remove CSS/Macrovision/Adverts/User prohibitions/forced subtitles/FBI warnings/... no problem.

It cannot bypass region codes with Matsushita (Panasonic) drives.
