SO since the region migrate tool, I migrated over to a UK XBL account and downloaded netflix. I was then trying to work out how some guys manage to get around the region block for SA. Here's how I've got it to work on Xbox:

First you need Netflix on your Xbox. I had to migrate my region from SA to UK so I could download it, see this http://zombiegamer.co.za/xbox-live-r...-tool-now-live

Then to get around them knowing where exactly you live, sign up for an 8 Day trial for Unotelly (http://unotelly.com/unodns/signup Basically a DNS Service thats tricks the services into thinking you in the US)

You can get a 30 Day FREE netflix Trial and Hulu+ Offers a 7 Day trial. So you can always try it for free regardless.

Unotelly provides pretty great step by step instructions and setup tutorials.

Costs after the trial periods:
Unotelly = $4 per month
Netflix = $7.99 a month, you get unlimited movies & TV episodes
Hulu+ = $7.99 a month, you get unlimited movies & TV episodes

I'm currently on a 2mbps line and its a bit fussy, but any episodes get pretty clear after a few minutes. I'm sure a 4mbps line would be awesome!
