I get copy protection in general. What I don't get is your particular intended use. Your situation is not
analogous to a game disc. First of all, a game disc is a pressed disc, not a CD-R recorded in a home burner. Thus, the game producers can do things to that disc that you can't do on your CD-R. Second, the game disc includes an executable (the game itself) that can make a decision as to whether or not it will run, based on whether or not it sees the proper copy protection mechanisms still in place.
If I understand your circumstances (which I admit aren't entirely clear - that is why I asked about your intended use), you want to burn some plain old files on a CD-Rs (e.g. mp3 files) that the users will access with their own applications (e.g. Winamp, Windows Media Player, etc.). For this to work, the files must be readable by any third-party application and by the OS itself, with no special drivers/decoders/etc. And that is where the problem is. If the files can be read by any non-specialized application, including Windows explorer, then they can be copied to the hard disc and burned to another un-"protected" CD-R at will.

I did look at the links you posted prior to my last reply. But I am still not convinced and don't understand how they can be effective. Playing around with the table of contents might stop a very simple-minded on-the-fly copy routine, but I'll bet good money that none of these protections will cause CloneCD, BlindWrite, Alcohol 120%, etc. to even break a sweat. And if the protections operate the way I understand you want them to and describe them as working (the discs are readable by ordinary programs), then they won't stop someone from copying the files one by one, either through Explorer drag-and-drop to the hard disc or through an ordinary compilation to CD-R in the likes of Nero.
I think you will find that these schemes offer very minimal protection at best - nothing that would stop anyone but the most novice of users, and maybe not even them if they think to just drag-and-drop. If that is sufficient for your purposes, then that is great. But I wouldn’t raise my expectations too high if I were you.
I am interested in being corrected if my thinking is faulty. Let me know which scheme you choose, and maybe I will try it for myself.
