 * DVD control protocol:
 *
 *     the TM-1 opens a drive control file using the DVDCtl_FILENAME; 
 *     this file can be used for doing authentication, as follows:
 *
 *           1) the TM-1 gets a (the) drive id.
 *
 *           2) the TM-1 generates a 10 byte drive random 
 *              challenge, and writes a block of 12 bytes
 *              to the control file, the first byte being
 *              DVDCtl_PutDrvChallenge, the second the drive id,
 *              and the others the challenge data.
 *
 *           3) the TM-1 reads 7 bytes of drive response,
 *              (DVDCtl_GetDrvResponse, drive id, and data)
 *              and does a drive autentication using the
 *              DVDD library, dvddDriveAuth. This dvd response
 *              is triggered by step 1.
 *
 *           4) the TM-1 reads 12 bytes of decoder challenge
 *              (DVDCtl_GetDecChallenge, drive id, challenge).
 *              This dvd response is triggered by step 1.
 *  
 *           5) The TM-1 generates a 5 byte decoder response
 *              using DVDD library, dvddDecoderAuth, and writes
 *              7 bytes to the control file (DVDCtl_PutDecResponse,
 *              drive id and data).
 *
 *           6) The TM-1 writes 1 byte, DVDCtl_GetBedk, to
 *              the control file, for triggering step 6.
 *
 *           7) The TM-1 reads 2047 bytes of DVDCtl_GetBedk,
 *              drive id and encoded embedded
 *              disc key, and passes it to the DVD using 
 *              the DVDD library, dvddComputeDiscKey.
 *              This dvd response is triggered by step 5. 
 *
 *           8) The TM-1 writes 2 bytes, DVDCtl_GetBetk and 
 *              drive id, to the control file, for triggering 
 *              step 8.
 *
 *           9) The TM-1 reads 7 bytes of DVDCtl_GetBetk, disc id
 *              and encoded title key, and passes it to the DVD 
 *              using the DVDD library, dvddComputeDiscKey. 
 *              This dvd response is triggered by step 7.
