Not sure if this is old. After any Q-Check PI/PO Test, DVD Decrypter with the default settings will only read (R mode) at no more than 2x speed. Copying files from the disc using copy command in XP is also very slow.
But after setting DVD Decrypter to read at MAX speed and let it read a disc a bit and the drive is unlocked. Copying files from the disc using copy command in XP is now fast again.
