DVD+R/-R Double Layer writing performance and quality:

The ASUS DRW-20B1LT 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 12x. Unfortunately, we didn’t have any media that was supported at this speed.

DVD+R DL:

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 BenQ DW-1655 using Nero CD-Speed.

Overall good results with these 8 X DL media from Verbatim.

DVD-R DL:

We regret that we do not have any high speed DVD-R DL media for our test; we will however show you how the ASUS DRW-20B1LT performs with our 4X media from Verbatim.

High PIF shows the ASUS DRW-20B1LT does not write to this media well.

Summary:

The ASUS DRW-20B1LT writing quality on our tested DVD+R DL media was good; however with high PIF on our DVD-R DL media, we would say the write quality is poor.
