[larry cui]

I'm trying to write dvd-r disc.
encounter the error "Command Sequence Error", both ATAPI(sony dru-500a) and 
SCSI(Pioneer DVR-s201 drive) on windowsNT/2000

My writing command sequence is as following:

1. Set the Write Type field in the mode select parameter Mode page
  to "Disc At Once"
2. Send DVD Structure to send user specific data to the drive

3. Specify transfer user data size by using the RESERVE TRACK/RZONE  Command

4. Read Disc info to get OPC infomation, send OPC info to the drive

5. Issue Write(10) to write data from LBA = 0

6 . Repeat Write(10) for all the data.
