I bought 1 pack and yes, they are MCC004. The problem I have is that my Pioneer 108 (with 1.18 firmware) will not burn them at 16x. They burn nicely at 12x, but so do the cheaper 8x MCC003 Verbatim +Rs.
This is too bad because I paid a lot more for these than the 8x (about 3x as much), and I didn't need the extra media. The only reason I bought them was to try 16x burning on true 16x media. (I've tried a few 16x burns on TY 8x +Rs, but although Nero lets me select 16x, the 16x speed never kicks in (never gets above 11.8x). I thought maybe with "true" 16x media, I'd see the 16x kick in at the end, but it was not to be.)
For me and my Pioneer, these perform exactly the same as the 8x disks. Perhaps a future firmware update will burn them at 16x. For now, 22 of the 25 disks are just sitting on my shelf waiting for that day to come. :rolleyes:
