The reason why alot of Princo manufactured medias uses the TDK G02 MF ID is because with this ID, the meda woul be accepted to be burned at 2X on the A03 and A04 units, Princo had no interest in paying royality money to Pioneer just to have their medias certified for 2X, thats why they faked the MFR ID instead. The issue is not so much "Beware! you are using fake TDK medias", this "phenomena" has been known to the industry for a long time, and was just a political counter strategic move from Princo. However, the method could ofcourse be questioned. The problem when Pioneer decided to "ban" this media was that alot of brands, like Bulkpaq, Choice, Datawrite/Datasafe, Eproformance etc.. hav had their medias manufactyred in Princos facilities, they did not personally know that Princo used this fake MF ID. There is alot, yes ALOT of different branded medias on sale in Europe with this stamper.
