My experience is pretty much same as chas0039's. Bought Verbatim DVD-R 8x made in Taiwan, all scans of each burn(NEC3520 @8x, @4x, BENQ1620 @8x @4x, @4x much better than @8x for both writers and NEC3520 burns better than BENQ1620's) just look like CMC disc, the high PI/PO values on edge. Switch to TY disc, the Verbatim makes more profit by selling crap disc made by the CMC.
