Ok, so I know that the streaming and downloading movies straight to your TV is on the rise, and as I might be moving abroad soon I figured this would be a great way to watch movies over there.

There is Roku (Netflix), AppleTV, Vodo, but which service would you recommend? I have a Netflix subscription here and would keep it if it would mean I could watch movies over there.

The requirements are:
1) Must work abroad and must have the ability to 'buffer' the movie before watching it (i.e. download it locally) as connections where I am going are not of the same speed as in the US
2) Must support high definition content
3) Must have HDMI output and be high def 720p/1080p

No need for wireless right now.

What are your thoughts?

Thanks!
