I have some Sony CDRs with a Sony media ID and yellow label in a 50 pack. These absolutely fail to burn, problem with writing Lead-in, on my Plex. Premium, Liteon 1693, and NEC 4570. I can get them to write on my Liteon 165P6S and the write quality at 24X is a little better than CMC at the same speed.
I will not be getting anymore of these when the 50 are gone. Anyone else, be alerted.
