Alright. I understand the basics of copy protection. That is to say, I have been working with computers for 10+ years and have read several wikipedia pages on the topic.

My question is: Why does, more often than not, a standard bit-stream copy of dvd fail? What happens when you make what should be an exact copy of a disk that makes the disk not work in place of the original, and how does software that beats copy protection do it? Ultimately, why/how does the linux dd command fail at producing perfect copies of any media?
