bet365 live streaming auto stop/play script

For stopping bet365 live stream delay i have to press "Pause" on the streaming video player until the video stream catches up, and then press "Play". I fed up with this rituel and rapidly pressing stop/play button every 2 minutes.. So i want javascript that add to bookmarks to make that automaticly. 1. Script must be work on both firefox and chrome. 2. I want to decide refrest rate of the script.
