Looks like we're live online this afternoon http://www.myp2p.eu/broadcast.php?matchid=106876&part=sports
Sadly, looks as if you do. This from the BBC's own site: Do I need a TV licence to watch video online? If you use any device to receive television programmes as they're being shown (live) on TV, the law requires you to be covered by a TV Licence. It makes no difference how you watch TV - whether it's on your laptop, PC or mobile phone or through a digital box, DVD recorder or TV set. You will not need a TV Licence to view video clips on the internet, or with the iPlayer, as long as what you are viewing is not being shown on TV at the same time as you are viewing it.
Haha, I'm certain it's illegal to view these streams (Hence why one calls them illegal streams) so viewing them with or without a TV license probably won't make much difference.
