help! I made an audio file that has two channels in fcp. when I play it through itunes in my computer or on my ipod it plays it in mono with both channels coming from both speakers. In fcp and after exporting it on another computer it worked fine with the headphones I was wearing. Can you help me? I'm an artist and I have a show on Thursday so it is imperative that both channels are split and coming from different speakers.

thanks
