I have 2 SATA burners, both from LG: WH12LS39 and GH22NS30 and while checking for their capabilities informed by ImgBurn, I saw that both can read and write on DVD-RW Dual Layer discs. Only there are 2 problems:
1) in the docs I could find online for the 2 drives, they never mention "able to read and/or write to dual layer rewritable DVD", they only mention single layer rewritable DVD;
2) I can't seem to find any DVD-RW DL or DVD+RW DL online for sale, to purchase and check.
How is that capability determined?
