Since the iPod Nano (which I have), Apple have taken away Firewire compatibility's on the iPod, which includes the iPod Video.
However, when my iPod is plugged into the Mac via Firewire or into the Firewire charger, it charges. There must be some Firewire compatibility in order to make that work.
I was wondering if there was anyway to tweak the iPod system software to make it work via. Firewire. I wasn't going to do anything about it until my warranty runs out.
