I am bothered by this too and from two friends I got these tipps (not tried it yet): One is using full VPN solution (US-based I think) and the other is just using a Canada-based DNS server.

BTW the problem extends beyond subtitles. International movies typically are just available in their original language + local translation (German). Then sometimes the video stream also differs from the English version (e.g. when there is a sign in German language).
