I just dragged the files to itunes. NO, the files are still working, same on the ipod. The non-mac audio books are all ipod compatible- but they want you to use the dreaded windooooz - they can be burned to CD- but again, I need to have some time with hi-speed in order to figure out how best to handle this situation- there are two Heyer books I don't have and they are in this format.
