I'd like to figure out how to use proxies to gain access to internet TV channels that operate a country block.

I've tried using regular free proxies and using them in my browser but it doesn't seem to work.

Here are two examples that I'd like to get working outside the US:
http://www.tvland.com/video/
http://streaming.myfoxny.com/24/index.html

If anyone could figure a simple way of doing this I'd be extremely grateful...
