the same thing happened to 30 gig video last spring, it only played in the left headphone on all headphones, i bought it at Cosco and took it back and they gave me a new video and a 50 dollar bill cause when i bought it over a year before i paid 50 bucks more than they sell them for now. i would take it back to where you got it, or send it to apple unless you really have your heart set on a different one.
