[quote name='Vinny']You have to use iTunes to access an iPod. I'm not sure if any other app will recognize it but you can only put songs into your iPod via iTunes (as far as I know).[/quote]
Actually pretty much all programs support the iPod, every popular one that is. I know Windows Media Player does as well as Realplayer. There are many more out there as well but names elude me.
Anyway, Apple and iTunes are your best bets. Try using iTunes first and if that causes issue then contact Apple, they should be able to help you.
