Lol, I'm in QLD so yes, highly likely I pay more for my electricity than you do.

Using Win 7/OS X with Firefox. Did you see the time at the bottom of the black screen? If so then the plugin is working (not sure which one, seems to have been on mine already). It worked last month and I found that if you have a black screen and the time stands still at the bottom then the session was over.

Come to think of it I might have used my US VPN though.

EDIT: Just tried a previous session and yes, it doesn't play without me switching on the VPN.
