Hi, Thomas
Thanks a lot for your patient explanation!
I've got much from your teaching, and we have adjusted the approach for the problem.
We are to create one or some "bad tracks" on the media to prevent duplication. This approach has been proved to be feasible because I know there are some equipments employing it.
How can I add bad track on the disc or in the iso image using project libburnia, or other project?
Thanks a lot!
