ok, so i got the 80gb Classic (6th generation), great device, 100% happy, looks good and feels solid, but as i was convinced i needed an ipod by my son for car journeys, who suddenly doesn't have anymore great advice, I now find myself in need of a wee bit of advice from the more experienced folk here at macrumors, what is the best way to convert some existing AVI films on my mac to mp4 for the ipod and what's the best way to set up itunes? i know i'm sick of the auto sync, tar
