Watching something in English in Germany
I've just spent an hour trying to change the language on my rented film on my new Apple TV. I am English and live in Germany. I have a German iTunes account and my billing address is in Germany. So, why is it so difficult that I can't change the language on my downloaded (English!) film from German to English? The whole point of me buying the Apple TV is that I can watch something and choose which language I want it in. Jeepers, I could have simply carried on buying DVD's. Yes, I understand there may be tax/copyright issues buying something from another country (although I never have these issues with Amazon) but language?
