Update on the international availabilty:
The video should be available on iTunes in the coming days in every territory that includes a "Concert Film" category. No subtitles required. Amazon and Google availability will still be restricted to English-speaking territories only.
The Concert Film category loophole was something that we were just made aware of in the last week, so thank you for encouraging us to look into it further. Hopefully you should see it appear on iTunes in the coming days (assuming your country's store has a Concert Film category).
Enjoy, and thanks again for the constructive feedback!
