My GQ -R 8x media (TYG02) has the following on the inner most ring by the hub: F4D04033664.
I'm not so sure they are fake (as in counterfit), but, rather, discs that did not meet certain quality standards. TY then sold them for 1/10 the cost to a wholesaler, who in turn, packaged them for various vendors like Fry's under their 'GQ' label. In any event, depending on the burner, the results could vary anywhere from 'acceptable' to disaster, even at 8x.
I learned my lesson.
