I did get to watch Tennessee play and get beat last week. I did that despite the fact that content is supposed to be limited to US IP addresses.
Here's how I did it.
I downloaded a free VPN - that's a virtual private network. If you use a laptop away from work to access your work network, that's what you're doing. Work ones are supposedly secure and often have a little key fob thing which gives you a code to access the VPN. This one was just downloaded onto our laptop (scary - eh?) and then you power it up. It's aimed at freelancers and other folks who are using wifi in airports and punching in credit card numbers or whatever.
Anyway, the VPN's servers are based in the US. So when I accessed the internet through the VPN, it appears that I'm in the US. So CBS lets me watch football.
I'm now looking for a VPN that will let me access a site where I can watch the Tennessee Volunteers win.
So, for reader Sam, who wants to watch premiership football aired in the UK or cousin Dana who wants to watch the X Factor (which, btw, I'm starting to get into) or whatever, this solution won't help you.
Although maybe there's a reasonably cheap VPN based in the UK? That might be worth looking into. I also investigated options for proxy servers where you tell your PC that it's actually running from Guam or whereever - and there were both US and UK proxy addresses. But I couldn't understand the instructions about how to do it, never mind actually get it to work.
