google sop cast. Go to there website, download it. There is a mma channel on there that shows every event. Its a live stream, basically its like tv. If you are on that channel it will stream it live to your computer so you can watch it. I don't recall the channels number off the top of my head. But it may not show up if its not actually broadcasting.
But install the program, and when its about time for the event to start just open it and scroll down looking for mma channel
