I also never used such utils, sorry...
...but....take a look from other side...even if you encrypt your music...dont think that this will prevent your CD's from being copied all over (at least if they proove to be a potential big earners). You need to know that hackers and crackers are always a step ahead...or at least walking hand in hand with manufacturers of such encryption software....so i dont believe that this protection will last for long...but...if you believe its worth to try....then why not...go ahead and let us know later of the results...
oh...and Welcome to the forum!
SiliconFreak.
p.s.
Dont think that i support illegal activities like copying or anything...its just that i am being realistic...and the point is...that so far...NOONE has find some unique 100% protection against copying,viruses, spyware,adware,and everything else....so i dont believe thats gonna change soon.
Good Luck with Your protection and I wish You get many many buyers of Your CD! btw...what genre is the music that you make?
