There seems to be some truth to the Unblock-US tutorial.
I initially tried a CDN unit bought at Mem Express in Winnipeg and it would not display the US-only apps using Unblock-us or a VPN.
I returned it and purchased a US model from B&H Photo and it worked perfectly with US apps (Netflix, Hulu, Pandora etc…) and the Unblock-us service.
This was in January 2012. I suppose Costco (or others) could have gotten their hands on US models to sell in Canada.
