Just a quick tip for you Lightscribe users-
even after installing the high contrast utility, my dvd labels were still unacceptable with my HP dvd840 burner. So I used Photoshop to crank the contrast way up, I also had some color photos on it that I put into grayscale, then wound up the contrast on them too.
After burning the label it looked much better. then I burned it a second time and they are coming out great. I am doing a slideshow as a gift for christmas for my relatives, the results are great.
just wanted to share
