I use the LaCie D2 Dual Layer+Lightscribe with my 667 Powerbook. I love it and use it all the time. I had only used the Lightscribe a few times since I got it in April...until today. I am making some DVDs for my brother and wanted to label them. I got an error message for the first time ever, but the message also had a link and suggestion to update the software. Clicked the link>took me to LaCie's website with two updates to download>took 5 min. for both and now burning away!!
Love LaCie....Get it....but get the newest Toast (on sale at MacMall).
