I apologize for bumping very old thread, but I would like to share my personal experience
of Lightscribe technology with fellow MacRumors members, and hope it would be appreciated
While purchasing the lightscribe discs, please make sure that:
1) Their origin country is not India (most lightscribe discs produced there suck)
Good lightscribe discs are made in Taiwan. Do not know about other countries yet
2) They are manufactured by famous reputable company, e.g.: TDK, SmartTrack, Verbatim
There are a lot of detailed FAQs at Lightscribe website, with many helpful answers
(including the explanation of whitish powder - it is not harmful, but do not eat

)

After installing Lightscribe System Software for Mac, do not forget to enhance the contrast
with a terminal command, for better quality:

For burning software, I prefer Disc Cover, but DiscLabel is good as well. Use high-contrast images;
if you are going to burn a color image, check that its appearance in black and white would be nice.
With best settings, it takes about 21 minutes to burn a large label. Pretty long, but the resulting quality is
truly professional-grade! We use Lightscribe discs a lot for promotional materials of our IT company, and sometimes receive questions from customers about from where we order these discs. They are always surprised when we tell that we make these discs by ourselves and without any special equipment -
just with $30 disc drive!
Personally, I am very excited about lightscribe technology, especially because after prices went down,
these discs cost almost the same as without lightscribe. I do not see any reasons why not choose them.
These gold color discs look good even if you do not burn a label. I like to use it myself from time to time,
for presents to friends and other different occasions. If you have any questions, do not hesitate to ask
