Preventing File extraction/ copy protecting a CD

Hi,

I am working on a tutorial cd for windows xp platform. This Cd will have an autorun file. I am trying to prevent the end user from copying cd and extracting files and folders from cd and in the mean time, cd content should be accessible/used without user interaction ( no password and such).

I know of a program called ISObuster which passess all copy protection methods in just seconds.

What would you suggest to fulfill my goal and also defeat ISobuster?

Is there Any encryption method capable of providing above requirements?(i.e. no password requirement to use the cd content, in the mean time have the cd content encrypted and accessible for windows xp/users)

thanks for your input.
