steve98:magu:ankit816:JonoNZ: Sky News UK is available on my Apple TV logged into the US iTunes Store. Works well from here too (no proxy or similar required).
So if we login with 2 apple ids on the ATV (1 NZ and other US apple id) would it show Sky News UK app? Would it matter which one is set to Primary?
Yes, but it's a pain in the arse to use: http://howto.cnet.com/8301-11310_39-57523804-285/how-to-add-manage-multiple-apple-ids-on-the-same-apple-tv/
If you're likely to want to use this a lot, just leave it set to the UK or US. You can still access your iTunes Home Share from your computer, the only reason you'd need to switch back to the NZ region is if you want to rent a movie from the NZ store.
Thanks magu and steve98
