This problem has been perplexing me for months now.
Ya, I think I got it!
I noticed that, sometimes I got a LOT of C2 errors on a certain disc, and then, I test another CD of the same brand and it would give me NO C2 ERRORs.
I just didnt understand the problem. I mean, I burnt one CD and the next CD after like 10 mins. Both CDs came from the same package and the same brand and everything... but.. one CD had a LOT of C2 errors (towards the end of the CD) and the other HAD no C2.
Finally, I figured out the problem:
Nero finalization causes C2 errors!!!!!
It makes sense because even my imported TY discs gave me C2 errors
