What do you mean by disabling the feature? If I understood correctly, one can use cmd.associate() instead of
cmd.transport() to send subsequent commands to the device. If that's the case, then I'd opt for the cmd.associate()
version.

Or are you talking about changing some code in the dvd+rw tools?
