I live in France, but prefer German Netflix.
A friend from DE once gave me his password, then I registered here in FR and actually had German Netflix!
Unfortunately, others are already using his account so there's no more space for me, so I have to create an account myself.
I'm thinking of creating a Netflix account when I'm in Germany again, with a German card and a German billing address… Shouldn't it work?
Why exactly was I able to use German Netflix?
You'll need a decent VPN service sooner or later, if Netflix updates its database, then…
As a little tip: VyprVPN
