The kids @ the high school look upon secured CD's/DVD's as a challenge. So far the 3 (2-14 YO and a 15 YO) have not been stumped. They actually check out CD's/DVD's from the library, break the security, and make a copy. I challenged them on the 05 code about 2 months ago and it took them all of 10 minutes to breach the security lock and make a clean copy.
