Hi.
Just speculating but, Doesn't this look like the restrictions already in place to stream video from countries different from the one you're in? (i.e: I can't stream video from US's Disney homepage, I'm redirected to my home country's page)
However your IP address is in the same country as it was with your other device...
This could mean the proxy is an option.
A friend of mine uses a UK's IP address and a VPN to stream video from the UK to Spain...

Just my 2 cents.

Regards.
