You could try setting up the Tor system, but it's very slow and not really suitable for streaming. It's also a bit complicated to do sometimes.
However, it's only free from the BBC because we in the UK pay a license fee, so if you don't pay this (I assume you don't if you're not in the UK), then it's not really fair you get to watch it in the first place.
I really wanted it to watch the 6Nations rugby. The french arent paying the licence fee, so there must be ways around it. I would happily pay to watch live streaming of this event.
