Why does the demo frequently pause and buffer before it resumes play?
In some cases, firewalls block Universal Datagram Protocol (UDP) traffic, which is the protocol required to play streaming content. In those cases, the Player is forced to use the HTTP/TCP protocol, which causes buffering and pauses when there is network congestion. If possible, contact your network administrator and request that UDP traffic be allowed through your firewall, as this is the best means of delivering streaming video over the internet.
