Up until the end of Sept. all the Prodiscs I got identified as MCC's and even though rated at 4X, they burned at 8X. The newest ones I got are identified as Prodisc and if burned at 8X, all are coasters. Burned at 4X they're OK though. When these are gone, I'll find something else. Does anybody know who else MCC makes disks for cause they sure were nice!
