StrongVPN looks like a good one, though I have no experience with it.
I have used VyprVPN in the past, which met my needs 100%.
Basically, your web traffic will be routed through a computer (server) at the location of your choice. VyprVPN probably has the most locations, but I haven't done any true research to definitively back that up. It is definitely easy to use for anyone.
Mac in Brazil ----> ESPN You get Blocked...
Mac in Brazil ----> Server in Texas, USA ----> ESPN You don't get blocked!
As far as ESPN is concerned, you are connecting from somewhere in Texas, and do not get blocked.
The only downside to using a VPN is that the time it takes to route your traffic through a server in another country
can sometimes affect performance, especially if your Internet connection speed isn't great to start with. So, if you wanted to surf the web through a VPN, it
could give slower performance, but still usable. Since streaming (LIVE?) sports uses a lot of bandwidth to start with, you
may have performance issues depending on several factors, like your overall connection speed to start with.
That being said, tons of people use VPN services for this very reason, and have acceptable results. I would strongly recommend getting a good VPN service, like VyprVPN and try it for a month. If it works for you, keep it, if not, you're not married to the service.
Now, to get the content on your television,
we'll need an adapter of some sort. I assume you have HDMI connections on your television, and for that, you'll need a (thunderbolt?) to HDMI adapter + an HDMI cable.
There are a lot of unknowns here, like does your MBA have thunderbolt, and does your TV have HDMI...
