This is what we call buffering, and is usually a result of the internet connection at your location. A few things to try: First, give it a couple of minutes to work itself out. If it does not correct itself, try refreshing the page. Another option would be lowering the bitrate. This will lower the visual quality some but will help with buffering. You should also clear out all other programs so that the simulcast is the only one running. Finally, ask others to not use the WiFi or internet while you are watching.
