I have bought a new case of brand name CD's they are 700/80 32X CD-R. The problem is that when I try to burn them w/ Nero it'll pop out the CD and tell me to instert a "blank medium". These CD's are brand new. What could be a problem here. I am burning audio w/ it being much less then the full capacity. Anyone came accross this problem. This only happens when I burn audio.
