KeyDB
Specify the keydb.cfg file path. If the keydb.cfg path is set, Xreveal may look up the decryption keys from keydb.cfg when opening BD/UHD/HD DVD.
If you don't have keydb.cfg, please Google keydb.cfg. Download and place the keydb.cfg inside the default folder %APPDATA%\aacs\.
The latest BD/UHD may require new keys to decrypt, you need to keep keydb.cfg updated.
