Welcome to the forum.
From what I've read posted in these forums, it seems that it depends a lot on the replicator company that produces the DVD. Some of the studios have gone through more that one replicator until they find one that does a good job, and those same studios will actively replace defective discs for customers. So if they have a bad replicator, it is costing them money and they work to correct it.
