Where did you find certified 52X Fuji? I thought they were sill stuck at 48X, as that is all I have seen anywhere around here or on the Internet. It does suck that even the 52X Fujis won't burn at max speed on the Premium, but perhaps a firmware update will provide higher speeds with my favorite Fujis. I still got my 50-pack 48X Fujis for under $10 so I'm happy!
