DVD+R/-R Double Layer writing performance and quality:
The LG GH22LP20 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 16x. Unfortunately, we didn’t have any media that was supported at this speed.
For these tests we wrote an image file of a DVD-Video compilation of as near full capacity as possible with CD-Speed. We then used one of our Lite-On burners along with CD-Speed to test the discs quality; we then finally ran a Transfer-Rate-Test on our Optiarc AD-7200A using Nero CD-Speed.
Although PI and PIF errors are fairly low throughout the disc, the result is spoiled by the PIF spike.
We regret that we do not have any high speed DVD-R DL media for our test; we will however show you how the LG GH22LP20 performs with our 4X media from Verbatim.
High PIE and PIF shows the LG GH22LP20 does not write to this media well.
The LG GH22LP20 writing quality on our tested DVD+R DL media was not what we expected; with high PI and PIF we would say the write quality is poor.
