PI and PIF levels are high at the end of the disc with PIF levels out of specification and our read-back test shows a slight slowdown. The result could be better and we would recommend not over-speeding this media.

PI errors are fairly high but PIF levels are low and we have a perfect read-back test. The result is good.
Summary:
The Lite-On LH-20A1S has written our DVD-R media with very good/good quality and wrote all our test discs faster than their rated speed.
Let’s head on to the next page where we will test DVD R DL writing performance and quality……

Are editing those pictures to mislead poeple or wot!?


I am in the process of sending back a 600 pack of 'Bulkpaq 8X DVD+R' to SVP because I cannot get a single disc to burn past the lead in stage. Tried with old AND updated firmware.
Unless I've been very unlucky I'd say its an awful drive






Since then I have now purchased Verbatim Discs with the completely identical results.
Absolutely horrible piece of hardware this Lite-on garbage turned out to be for me. Never again!!




Judging the drive just by some cheap media isn't very logical. Try at least four different DVD media (incl. brands)
