If you sent us your disc for import/setup, we make an exact image file of what you sent us. If you did not carefully verify and test your disc, or used cheap blank media, our system has no choice but to duplicate any flaws on the disc. It's up to you to test what you send us and what we produce and send to you before you order lots of quantity for other people.
