Q: My video and audio does not play smoothly
There are many reasons why this might occur.
Your bandwidth may be being used by another application (or another PC, if your connection is via a home/office network). Your viewing experience will be affected if our servers are unable to deliver data to your computer quickly enough because of network congestion on your connection.
Downloading large files or using peer-to-peer applications while watching video, for example, may prevent you from being able to receive enough data to maintain a constant video stream.
If you do not believe your connection is being used by other applications or other people, check your media player has the correct bandwidth settings.

Q: What about firewalls?
Some corporate networks and Internet Service Providers block video transmissions. If you cannot see video clips (even though your system meets the system requirements noted above), you may want to contact your Internet Service Provider or Network Administrator to see whether a security firewall is blocking video transmission.
