According to Dakhaas (if I'm not mistaken, too much info running in my head :bigsmile: ), Datawrite MCC is not faked, but E-net would buy these directly from CMC Magnetics or Prodisc (who manufacture MCC media for Mitsubishi/Verbatim), not from Mitsubishi themselves. So the production line and quality control would be very different.
edit just see that Chancoluuk already mentioned the point while I was typing.. :bigsmile: - re-edit and Dakhaas also! :doh:
Besides, the mediacode doesn't refer to the dye per se. Common misconception. It refers to the overall characteristics/technology of a disc, and its purpose is to tell the firmware to use the relevant burning strategy. As JayC30 mentions, it can easily be faked: the apps "identifying" the disc have no way to tell if the disc is genuine or not, they just retrieve the mediacode from the "pre-recorded" info on the disc. Nothing else.
