First, check your internet connection. You need to have a broadband internet connection such as DSL or Cable. Second, make sure you don’t have any software running that is slowing down your connection. Finally, make sure you have the latest version of Adobe Flash Player installed. You can get the latest version here : http://get.adobe.com/flashplayer/ . If you still experience freezing every few seconds, try pausing the video for about 15 seconds before clicking the play button again: that should give the player enough time to buffer the video.
