Burned about 20-25 MCC03RG20 with the 109 (1.40) and didn't experience this. I don't have TYG03.
But I burn the MCC03 with Nero (I make data disks with them), not Decrypter (I generally use MCC02 with Decrypter).
Maybe there's something on with Decrypter, as these 16x medias are kind of new..? Do you burn them at 16x, actually?
Worker, do you burn your MCC03 with Decrypter?
