DVD+R/-R Double Layer writing performance and quality:
The Lite-On LH-20A1S supports the DVD+R DL/-R DL standard for writing Double Layer/Dual Layer discs with a size around 8.5 GB at a writing speed of 8x.
For these tests we pre-authored several video clips into an image file and burned the resulting image in Nero Burning Rom. We then used the Lite-On LH-20A1P along with KProbe to test the discs quality; we then finally ran a read-back test on our Optiarc AD-7173A using Nero CD-Speed.

The Lite-On LH-20A1S had big problems with this disc, the disc was un-readable, a very poor result.
We tried a second disc.
Once again the disc was un-readable.

PI errors are high but within specification, PIF levels are low however, our read-back test drive once again had problems reading the disc. The result is ok but could be improved.
Summary:
The Lite-On LH-20A1S burned our test DVD+DL with excellent quality. DVD-R DL quality was another matter. The 8x DVD-R DL media tests failed and our 4x DVD-R DL burn also showed some problems.
Let’s head on to the next page and our DVD-0RAM writing tests....

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)
