All Answers To Questions

Without knowing what kind of copyright protection is being used, it's hard to answer. I have never encountered copyright protection on those files. But I would assume if u loaded them into a converter of some kind (such as Super), U could strip whatever copyright protection from them. The same is true if u loaded them into an editor such as Adobe Premiere Pro. It would probably not keep the copyright protection on the edited result.

Attempting to "circumvent copyright protection" of copyrighted material is a federal crime in the USA and a violation of laws in the European Union, and many other countries, under the WIPO Copyright Treaty (1996). There is a minor exception for "reverse engineering" a copyrighted work for "interoperability". Dozens of large companies have sued people for distributing this sort of information for copyright infringement. There are those who claim that the interoperability exception "swallows the rule", rendering the law essentially meaningless.
