Copyright problems

I believe that you would be infringing copyrights by converting the material. That would be copying it. I believe the only way to do it without infringing the copyright is with the permission of the copyright holder.

But check me out on this. I would suggest you use the following link to get to the FreeAdvice explanations of copyright law. If that material does not answer your specific question, it will give you a good fast overview of the law:

If you want more info after reading the above, go to the US Copyright Office site at http://lcweb.loc.gov/copyright/. They have a lot of material there.
