Found these 40x CMC's at CD Dimension- http://www.cddimensions.com/cd-r_media/cdmedia-code.asp.
Thought I'd give them a try. I usually only use Mitsui or Taiyo Yuden and their 32x's and even most of their 24x's write at 40x but since these are one of the first 40x certified I am giving it a shot. I bought some no name ones and have CompUSA, which I hear are Ritek ordered as well.:eek:
