Why does the video sometimes stop or pause?

Our video uses "streaming" technology to start transmitting video almost as soon as it is requested, rather than waiting for the complete video file to download. If the video stream pauses, it is probably due to Internet traffic congestion, a slow modem connection, or insufficient computer hardware. If a pause persists, it is recommended that you restart the video.

What about firewalls?

Some organizations and Internet Service Providers filter or block video transmission. If you cannot get video transmission (even when your system meets the above computer and software requirements), you may want to contact your Internet Service Provider or Network Administrator to see whether its security firewall is intentionally or unintentionally blocking video transmission.
