All the TDKs at Best Buy are MIT CMCs. However, I don't know what the hell CMC did, but their 8x TDK media burns fantastic, better than Fuji's TY02s do. There's been talk elsewhere on the board about the jump in quality from CMC--apparently they're using Philips dye, which, from what I understand, is pretty good quality. Maybe the manufacturers were catching hell about the garbage 4x CMCs and told the manufacturer to get it together.
If Best Buy wants to play games with their Fuji media, screw'em. TY is making garbage now anyways.
