I'm in the UK and have one of my Apple IDs set to the US region. I've so far only linked my Movies Anywhere account to the iTunes account and haven't actually bought anything (which would require redeeming a gift card beforehand anyway). I was wondering whether others non-US members here use the US iTunes store to buy movies and TV shows (there's definitely more choice and more sales, and now with Movies Anywhere, UV codes can be bought for cheap and the titles transferred to iTunes)? My main concern is that iTunes will region lock the content so that it cannot be watched outside the US and I'd be locked out of my collection. Is it worth building a collection on a US account if you live outside the US or is it best to stick to your own region?
