Well, I saw the other thread where these were mentioned (here), that depending on what # you're using, usually CMC-made ones have the numbers all written together; the Prodisc-made ones have #'s separated by + or -; in case of DVD-R, that would be a minus.
The important number is the one around the center hole, stamped into the plastic. If those numbers are all together, it is CMC-made; if separated by + or -, it is Prodisc-made. OC-Freak made that very plain. :bigsmile:
Yes, the mah leading serial is CMC-made, and seems to indicate not a great batch, if I read the post in the other thread right.
