Lee, Du bist ein Riese in diesem Feld - you are computer tech giant personified. Thanks for the info. The more I know, the less I know, though. So I shall burn the disks in Audio CD. At least I don't have to worry about playing them on any player. However, when importing, there are those other choices: Apple lossless, AIFF ( I know about it), AAC ( is that this mp4 thing , Apple's own which resists a lot of things you want to do -- protected files, those you pay for and download? ) and Wav.
