The real problem with this protection scheme is that those original error codes were engineered and put in the CD recording format for a reason.....
"The ability for a consumer CD player to continue to play a CD without error if an imperfection was encountered while reading. Like a finger print or a smudge Etc.

Now with the newly inserted intentional errors introduced, the correction algorithm will be more prone to cause skips when actual imperfections are encountered by legitimate customers.
At the end of the day a customer will end up with less tolerant CD's that will play less accurately in regular players. this can easily be proven in a court of law.
and let me tell you - I really want to end up with one of these CD's so I can bring suit against the Record companies for invalidating the spec. I used to repair CD players and was educated on the tolerances of CD's for error correction. I used to use test CD's with specific flaws directly placed on the disc to test the correction algorithms in different players.
Let me tell you that the players are NOT made up equally and some fair much worse than others. I'm sure if this protection goes wide spread - very tiny imperfections will cause your $15.00 CD investment to not play worth a damn.

The consumer heat from this is very real. I will personally never buy another CD if this goes wide spread. And that would be a shame because I have certainly bought allot more CD's since being introduced to the MP3 world due to the sheer exposure to new music. Which is the REAL fear of the record companys as they do not want me to listen to anything they do not premote. *sigh This kind of stuff makes me very angry.
