Fake DVD+/-R 16x for sale

Fake blank 8x and 16x medias, branded TDK, can be found in Taiwan. They were reportedly made in factories that theoretically can't produce medias better than 4 and 8x. Actually, there are only 5 manufacturers only that master the technique to make 16x medias. Yet with the evergrowing demand for such medias, while it's getting down for slower ones, some second zone manufacturers took the risk of artificially modifying the specifications of their products in order to make more profits.
We do not know if such "overclocked" medias will eventually reach other latitudes.
