My iPod mini worked just fine, but the next morning the battery was completely flat. Seems too much of a coincidence that I used it with the Xbox, fully charged, for about 40 minutes, unplugged it straight away and the next morning it was dead. I'm going to have to try it again and see what happens. I've also noticed that I can no longer fast-forward or rewind using the standard controls on the iPod, but I'm guessing that's unrelated because I think it was happening before.
