Netflix in the UK (Cant connect - yes another)

Same issue with my wdtv live.

I select the Netflix icon in the “service” menu I constantly get the following error message “unable to connect to netflix. Please try again or visit: www.netflix.com/tv.help”.  502 in bottom corner

Firmware version is 1.07.18.

Tried multiple different DNS options including unblock US and open dns none of which work.

Have also rolled back to v 1.06.04 which did not solve the problem. Now back to 1.07.18.

Can access netflix from other devices fine. (PC / Laptop / Tablet and Smartphone).

Have a collegue at work with the same device and firmware level using open dns and he gets access OK.

Am I then to assume that its a dud device or has something changed in the manufacture of the item.

The item was bought online. Is there a way to tell if its a UK device or if someone is shipping in devices from abroad and selling them on. Would this cause an issue in connecting to netflix UK.
