We have changed the video buffer time to 10 seconds, it means when you click the "Play" button, video will download for enough duration (10 seconds) before it really start playing, that will make sure user can have a smooth watching experience after that.
If you want to configure your own buffer time, you can use FlashVars buffertime in embed code, for detail, please check
Customization Guide.
