Yeah it says based on Cactus but it isn’t CDS! The word he should have used was “inspired” not “based”.
CCD-Lock injects sub-channel errors (no where near the same as CDS does) has it’s own watermark, the TOC and lead-in and times are so fucked up that CD won’t play on DVD players (CDS will).
To answer your question freeware protections like CCD-Lock and others are much stronger than CDS since they don’t care if the CD plays in DVD players and have problems, comericial protections are much easier to defeat since they have to be sure it plays in 99% players. CCD-Lock will play in 30% or so, from what I can see and no DVD players.
CCD-Lock fucked up the TOC…forget that app and toss your CD good-bye, next time you burn important data back it up and stay away from these CDDA currupters they are not protecting anything, they’re fucking it up!
