Idk if it works for people outside of the Netherlands but I think the Dutch broadcasting station has a good site for this World Cup. Their streams haven't lagged for me yet and they have the neat feature that the bar permanently displays when and who scores or gets carded like so.

Just go to http://nos.nl/wk2014/ and click the red "Kijk live" if a game is playing. If it hasn't yet started you can go to http://nos.nl/wk2014/schema/#kalender and scroll down until you find the game you want and click that. o/
