US IP address for Smart TV

Okay, so I bought a Vizio Internet APP TV in the States and brought it back to Canada to enjoy the features but it doesn't seem to like my Canadian IP address. The wireless turn son and the tv connects but the APPS say there's no connection. Speaking with Vizio about this, they say it because the apps are into support in Canada so I may need a US IP proxy and program it into my router so the tv reads it.

My question is how do I program a US IP address/proxy into my router without screwing up my router. I run five computers off my wireless router with all different IPs.

Help would be appreciated C: if this is possible.
