If you know what a genuine maxell burn looks like (maxell 002, for example), and you compare it with something that is labeled Maxell, but comes up a different mid (like ritekg05) and you compare the burn graphs, then you know both ways what you have is not Maxell and just has an mid on it to make the burner recognize it as a certain mid to use that burn strategy.
However, unlike that engineering manager at MAM-A, there's no way I see someone using an mid code that's not theirs is legal, not in the US, anyway. If its a no-name company, well... I wouldn't buy from them in the first place. However, if I see a TY code on a media that doesn't have the quality burn of a TY, then I'm going to call BBB and whoever else to make sure said company knows I know it's fake and try to make it to where they don't sell that junk to anyone else. I mean, no offense...but if a retailer tries to palm that junk off on me as genuine TY, I'm going to be quite irate over it.
