Many iPod users have asked this.
It won’t be a problem if you use AVCWare iPod to iPod/Computer/iTunes Transfer.
It automatically transfers your iPod and iPhone music, video, playlist, photos back to computer and iTunes. Backup all your music and video in a couple of clicks. Really makes music and videos sharing pretty simple and enjoyable. Wish this can help and good luck.

I think its step by step guide is most helpful.
