I got an older 40GB Apple TV from a friend, but he didn't have the original power cable anymore. I've found a cable from an old DVD player that is an unpolorized C7 cable. It's rated at 2.5 Amps & 250 Volts. Will this cable work with the Apple TV. I know the power cables that come with the Apple TV are rated at 2.5 Amps & 125 Volts, but I don't know if that makes a difference? I don't want to fry the Apple TV.
