Answers:

Why doesn't the webcast appear when I try to launch it?

Many of our webcasts utilize pop-up windows. If you have pop-up blocking software installed on your computer, it may be preventing our webcast player from appearing. Try temporarily disabling your pop-up blocking software.

Why can't I hear any audio?

    Check the following:
  • Check to make sure that your speaker volume is turned up.
  • Check to make sure that the volume, for your Operating System's Volume Control, is not Muted or turned too low.
  • If a lower stream bandwidth or stream speed is available, try choosing it.
  • Shutdown the Media Player Window and access the Media again.
  • Internet Streaming Media requires a Streaming Media Player to be installed on the machine to watch video or listen to audio. You may need to install a Streaming Media Player to hear the audio.

Why can I hear audio, but can't see any video?

The Bandwidth, to stream both Video and Audio, may not be available through your internet connection. Streaming Media players often drop the Video frames and play just the Audio in scenarios where bandwidth is not larger enough for transmitting both Video and Audio.

If a lower bandwidth is available (such as 56k), try choosing it. Larger bandwidths require more network transmission space. Smaller bandwidths will ussually move through lines in a more normal fashion.

Why does the stream continuously buffer?

If the video was working before but now you are experiencing difficulties, the incident may be caused by a recent network configuration change. Check with your Internet Service Provider or your System Administrator if you have one. The Internet Service Provider or the System Administrator should be able to tell you if there have been any changes to the ability to stream media over the network to your computer.

This could be caused by Internet congestion. High levels of Internet Traffic and Network Traffic could cause this to occur.

If a lower bandwidth is available (such as 56k), try choosing it. Larger bandwidths require more network transmission space. Smaller bandwidths will ussually move through lines in a more normal fashion.

Why am I unable to connect to the stream?

Can I listen to a webcast from my company's network?

If you are within a corporate intranet, there may be local network settings that are impairing your ability to hear this webcast. Contact your corporate Network Operations or IT organization to see if streaming media formats are blocked at your corporate firewall or proxy server. Also, you can have your IT group configure your local media player to support HTTP-only protocol traffic over port 80. This may also help to resolve firewall-related issues.
