I have never found LightScribe to be good for labeling. On DVD in particular, the coating being on bottom of disc you have clear plastic between top and lasered label and it looks odd.
Contrast issues and very long time to make labels that are dark enough to read and possible fading of label over time all fight against the success of the idea.
I prefer top-coated printable. Consistent application for both CD and DVD (label always on top), speed is faster and using color is more beneficial to me.
After trying for a while, I just gave up on LightScribe as too much bother and too slow.
