that (U.S. based) proxy alllows Javascript and Flash?

I watch the Colbert Report and the daily schedule online, but will not let me see it from the United Kingdom. I tried a lot of proxy servers, but when I tried to play videos that always says, "To watch this movie you need the Adobe Flash Player. You also need to have JavaScript enabled in your browser to ".. so anyone have any proxy servers that enable Javascript and Flash Player? Please verify that you can watch videos through them before posting, thanks. Oh, and I have them installed on my computer, I can watch videos as often if not using a proxy (other than sites that are restricted location.)

Proxies are typically very poor in this function, if they work at all. A better approach is a personal VPN. Put all your network connection through the tunnel. Everything works as it is assumed that no problems.
