can my Optiarc DVD±RW ND-3570A ATA Device burn dual layer dvd’s? i can’t seem to find this anywhere…thanks!!
Hi evil genius mojo, welcome to CDFreaks! 
Yes, your Optiarc 3570 can burn to Dual/Double Layer DVD media.
I suggest using Verbatim DVD+R DL media for video and Verbatim DVD+R/DVD-R DL for data. This will give you the least amount of trouble.
