As far as we know, MCC uses the same dye regardless of where the discs are made. In the case of DVD's, there is little evidence that dye type has much of an impact on burn quality, it's the combination of burner/firmware and disc that makes for success. So just stick with brands or suppliers that you trust, and that work for your drive. I do not count Verbatim as one of those, certainly not Memorex. Although, with the NEC burners, all of the Memorex suppliers work just great. Buying TY in bulk is a perfectly good solution. If enough people did this, sooner or later the brand names would notice.
