I have a question on setting CD speed. I have tried to get the write speed by sending GET Performance command to the drive. After that, I got the list of writting speeds. Then I use SET CD SPEED commands to set the speed of drive and monitor the real writting speed. I found a strange phenomena: Once I set the minimum speed and do some writing operation, after that even I reset it with the maximum speed, the DVD/CD drives still use the minimum speed. Why? Is there somebody ever encountered this situation.
