I was able to get the movie to play once via VPN and then it stopped working (not available in your country).
Well i was playing on my nexus 4 and notice that there was no Play movies on the phone so when to all apps in the play store and find the app and enabled it.
I can now steam movies on both my nexus 4 and nexus 7 however i still can't buy from the NZ play store.
So i did a little test, i used a VPN on my windows machine and purchased a tv show via the play store website, I then tried to play this on both my phone and nexus 7 and both are stream/downloading it fine without any VPN or anything (connected just to my slingshot account).
Could this be a sign of something coming?
So if anyone else has a nexus 7/4 (anything else with movies) can you please test it :)
