Here is what I am trying to do. I have my music files on my Desktop PC. I would like to have iTunes on my iBook use the music folder on my PC as the default iTunes folder for music. I also want to be able to sync my library to my iPod from my iBook. I also need to be able to sync another iPod (my wife's) on the PC. I don't want to copy all the music to my iBook as the HD is too small. Will turning on sharing allow me to do this? I was under the impression that I could only listen to music using sharing. please help.
