yeah thats it mate... you shouldnt need to click the arrow though, it should open automatically (if not, click the arrow)... Just give it a few minutes to buffer and you should be up and running...
Oh and one thing you should know; the stream is usually around 2 or 3 minutes behind the actual game so if you have people who txt you when we score, turn your phone off!! It's ruined it for me a few times!!
