Seeing as I have a home in the USA but primarily live in Canada, would I be able to sign up for a US netflx account and access the same content in Canada without using a Proxy?
No Netflix takes your dns of your location and gives you the content from that location: so if your in Canada you have Canadian Netflix when your in the states you have American Netflix I believe.
I use this on my Apple TV and Mac - really easy to do, cheap and quicker than a proxy.I'm in Canada and access US Netflix with a service called Unblock US. (Not affiliated in any way) It's about $5 a month, very straight forward to use. I put the settings into my Time Capsule and any Mac, iPhone or iPad in the house get's US Netflix. Once in awhile, there is content that I want on Canadian Netflix that isn't in the US, and it's very simple to switch back.
