I currently own a LG GSA-4166B drive. When I burn a Lightscribe media using SureThing 4 SE, I have noticed that on dark parts of the images, you can see circular swirl marks on the printed disc. I'm using the latest firmware and Lightscribe System Software.
I used to own a HP 640i and swirl marks were never visible on the dark parts of the images. Does anyone else face this problem? I have always been using the Verbatim media.
