I already posted in my previous post about free sites for watching cricket world cup. Now you can watch it officially with ESPNstar.com with high quality straming links
. You can watch it in the embedded player , if it is not working then visit following links these are direct links and no misguiding links like other sites.

1. www.espnstar.com/cwclive
 
It is official live broadcast. It is the high quality broadcast so streaming may be slow. Please visit other if streaming is slow but its a 100% working link. Live telecast begins after 25 seconds ad.
