I think you misunderstand the difference between Brand Name media, the media code, and fake media. Most brand names are not made by the company that brands the label. Also, most branded labels will sell many different media codes under the same label. This is one of the reasons so many of us avoid branded labels; we never know what we will actually receive. Maxell is a good example; they have, at one time, had 11 different comapnies making their DVD media.
Fake media is a different animal. Fake has nothing to do with the label on the disc. It is when the media ID is not really that of the people who make it.
