and here are Lite-On LH-20A1H LL0A FBD scans at 8x, 12x and 16x with the same media tested above. I didn't expect that 20A1H would support TE/FE test. the 20A1H tests take minutes whereas 1635S "tests" take seconds

one question, is the drive and/or the burn affected by the DVDScan's TE/FE test as BenQs are??
