OK, I just got to ask, how does one go about copywriting someone elses material.

Unless it is a phillips device, (a fraction of a percentage of the entire database), how is it that they can copywrite pioneer codes. Even if they are in a different format, they still work pioneer equipment. Does this mean that I can go buy a book, record it into audio format and than copywrite the new version myself? After all, I did change the format.

Please enlighten me.
