Hi,
there's no easy way to protect your CD from copying, but there's to solution, one is to provide you a website of manufacture that make an encrypted CD, so the user can play the files only when the CD is in the optical drive,
my other solution is to edit the video,text and images by adding a watermark to them, and for the exe i need to check it first to see what i can do for it,
anyway if you need that, contact me
