DVD+R DL/-R DL Writing performance
The Lite-On LH-20A1L 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.
DVD+R DL:
For these tests we wrote a full disc with CD-Speed. We then used the Lite-On LH-20A1L 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.

PI and PIF errors are extremely high on the second layer and our read-back drive had problems reading the disc. The writing quality could be improved.

PI and PIF errors are extremely high and out of specification. Our read-back drive was unable to fully read the disc. A poor result.
Summary:
The Lite-On LH-20A1L writing quality with our tested DVD DL media was very disappointing and requires some improvement.
Let’s head onto the next page where we will take a look at DVD-RAM performance….
