To download anything about MMA you need to be on MMATRACKER.
You need to be invite by someone who is already a member of this torrent site.
I am a members but 3 weeks ago i invited 4 guys and my invite and down to zero for the moment.
To watch the event live for free on the net you can download TVU and watch the channel mmatv.
You can also try to be a real member of mmatv by creating an account on www.joesondo.org but sometime it doesn't work.
If you were able to create an account on www.joesondo.org you can donate and become a premium member like me, premium members have reserved personal stream witch guarantee that you will be able to have a stream when a lot of peoples are watching it and the slots are full.
Premium members have a lot of feature of any kind like video vault, on demand , etc... etc...
that's it !!
Good luck !!
