Any info about MID of these discs ?
CMC MAG.E01 according to videohelp.com. No sense in getting those when you can get 50 YUDEN000T02 from Rima for $4 less: http://www.rima.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=R&Product_Code=1733-50
Two Degrees, I've heard HP 8X +R being MCC003?
Doesn't seem to be as common as CMC though. I wouldn't want to chance it.
