I have all the required plug-ins but I am having trouble viewing the program in the classroom, what should I do?

If your internet provider is Comcast and you are using Internet Explorer, you may experience connectivity issues. If possible, please try using a different browser instead, such as Mozilla Firefox or Google Chrome, and the programs should play smoothly. Otherwise, please try the following.

First, go to 
This will tell you if you can connect to our server. If the RTMPT connection is a success, you should have no problem viewing our streams. Some customers from larger organizations have expressed the inability to connect to our servers. We use standard HTTP tunneling over port 80 to stream multimedia.

Second, if you receive a success but still cannot stream our multimedia programs, go to: - this is Macromedia’s port connectivity test. This will tell us that you can in fact connect to a Flash Communications Server over the specified ports. This page has lots of helpful information regarding how we connect to a customer’s computer.

Lastly, if any of above fail, have your system administrator add the URL for our streaming server (IP address - to the firewall rule for port 1935, 80, 443. Ask them to make sure that standard HTTP tunneling is turned on and not proxied HTTP tunneling.

Please contact your system administrator should you require more help on this issue.

The media stream is inconsistent, sometimes smooth sometimes choppy. Why might this be happening?

Streaming multimedia from the Internet is resource intensive on your computer's memory. If you have multiple programs open, such as Microsoft Office applications, this can degrade the performance of the multimedia stream. If you experience poor performance, try closing some applications. A typical video stream will take up 25 - 40 MBs of your computer's RAM.

Streaming issues occur most frequently with Internet Explorer. If you are using IE and experiencing streaming issues, please try using another browser such as Mozilla Firefox or Google Chrome.
