Netflix have enabled a download feature on their mobile apps today. It looks like this has solved the issue where you couldn't airplay US content while connected to the US VPN (it works if you download it first now).
We'd be interested to hear if you've managed to get this working, and if there's any other features which changed with this release.
I’m really fond of streaming and watching Netflix, Eurosport, BBC iPlayer, Sky Go, Pluzz and a few other channels without buffering. I even access some of the most popular websites that are blocked in some nations. My VPN service provider (AceVPN) works well with a host of network-connected devices, PCs, Smart TV, and gaming consoles. But I’m not yet to understand how they work.
