If you want to watch the WBC Lightweight Championship boxing match 'live' (just a delay of 2 minutes or so) on June 28 (June 29 in the Philippines) between Manny Pacquiao and David Diaz via online streaming for free, just log on during fight day at the Sports section of MyP2P.eu (around 8 a.m. or so here in the Philippines) . There, you'll find a link to the Boxing page of MyP2P.

If you haven't done so yet, you need to download any or all of the following P2PTV clients: SopCast, PPLive.com, PPStream, TVAnts, or TVUNetworks. (Sometimes, all you need is the latest version of Windows Media Player, and you will be able to watch the channel on your browser). Usually, it is the SopCast links which work, (followed by TVAnts).

On the Boxing page, you'll see ratings of the different peer-to-peer channels. Just click any of the Play links, and the particular P2PTV software will launch a particular channel. If a link doesn't work -- meaning the channel is offline -- try another down the list. I suggest you log on to MyP2P early so you can try out the best TV streaming channel. 

Of course, you also need to have a broadband connection to watch the match (to be held at the Mandalay Bay Resort & Casino, Las Vegas, Nevada, USA). Hope this helps without you paying a fortune for pay-per-view.
