UPDATE 05/2012: If this isn’t working for you anymore, you might want to try this new method.
UPDATE: Some visitors are reporting that this works for Hulu as well.
The relationship between Comedy Central and Canada’s Comedy Network is the worst example of what can happen when rights owners assert copyright on the internet, based on national borders. If you are not aware – like Hulu, TV.com and others – Comedy Central videos will not play in Canada, but it’s worse. ComedyCentral.com – the entire domain – is unavailable to Canadian IPs! When you try visit it, you are redirected to comedynetwork.ca.
I found a workaround to this buried in a comment thread on reddit. Firefox users only:
For Canadian viewers, if you are using firefox, install the following addon:
1) In Firefox, Go to tools->modify headers
2) From the drop down box on the left select add
3) Then enter: “X-Forwarded-For” in the first input box without the quotation marks
4) Enter: “22.214.171.124” in the second input box without the quotation marks
5) Leave the last input box empty, and save the filter, and enable it
6) Click the ‘Configuration’ tab on the right then proceed to check the ‘always on’ button.
Close the Modify Headers box and it should work.
Works like a charm!
