Possibly stupid question: why didn't some enterprising person figure out how to produce CD-Rs with the copy protection wobble track? Is the market too small vs the cost of required equipment? Would it have been illegal?
"I hope this lays the matter to rest, and prevents anyone from wasting more time on it (like my day burning useless discs).
I'm sure someone will wave their hands around and say that custom burner firmware could do the job, but good luck finding a burner with a programmable DSP in the pregroove tracking loop and managing to modify it to do the job."
