iPod's play a file format called AAC. You should check the directions/help files on the ipod itself to see how to transfer files. The files on P2P networks are almost all in mp3 format. The ipod website indicates that your iPod will convert mp3 files into AAC files. I think this is a question for Apple and not Limeware. Have a look at the directions, check the iPod website. It shouldn't be too difficult.
