How come Liteon's running OPC (OHT) isn't as deep and often as Benq's WOPC on the DW165x (and 1640?) and Plextor's PowerRec on 755a and 760a (when burning at 16x anyway the burn graphs for the latter 2 are like a jigsaw)? is it just a different method? Does it not check as often? which having less dips seems to indicate.
It seems to be about the same as the old 716A.
