sciacca, I just downloaded and used the AveryPro software for Mac. Neither Pages nor Word really has an easy answer to printing CD/DVD labels.
I needed something quick and easy to put together a label for some pictorial/video DVDs our family hands out at Christmas. AveryPro did the trick. Quick, simple, looks great. I quickly imported a picture, set the text, calibrated my printer and 20 DVDs are done.
Perhaps I could have put together a template in Pages or Word, but I really didn't want to spend all the time getting spacing, etc., right. About 30 minutes, start to finish, AveryPro was downloaded and all my DVDs were completed.
