I have no doubt what I highlighted would be your problem.
Try some TY discs or Verbs with MCC dye.
If you want persist with the ones you got, then lower your burn speed and see what happens, altho this is not really a fix, the discs are just shite.
Forget the lat bit, I see your drive only burnt them 6X anyway even tho you selected max, just while you're at it, you might want to check for firmware updates for your drive.
