I have a mac mini. Today I received two replacement cd's for "ilisten" - a dictation program (thank you Chuck and Janis Rogers of MacSpeech). Obviously the problem is my computer and not the disks. I put Tina Turner in - itunes opens and she is ready to rock. I put the two disks in from MacSpeech and they show as blank recordable disks. I have yet to learn to burn a disk. I certainly can not figure out how to change any settings or determine what is going on that my computer can not read these. Can any one help me, please?
