Minimum Requirements

First, confirm that your computer, browser, and Internet connection meet the minimum requirements for streaming or downloading. If they do, and you still have difficulties, review the common problems and solutions below.

Cache

Periodically clear your computer cache by using Disk Cleanup in your System Tools. Also frequently clear the Internet Explorer cache under the Tools dropdown menu.

DVD Streaming and Downloading

In the effort to enhance your viewing experience on occasion we will have a folder that contains a movie file ending in .wmv or .avi. This will take a little more time to download and will open in Windows Media Player.

Java Virtual Machine

If you are using Microsoft Internet Explorer and experience problems while viewing or closing the recording, we recommend upgrading your Virtual Machine. It can be downloaded from www.java.com/en/download/manual.jsp.

Pop-UPs

Disable pop-up killers, at least for this portal site. Many of these pop-up blockers sense the video window as a pop-up.

Streaming Files

Each class or presentation has three separate files: one for just streaming, one higher quality download, and one lower quality download. If one file will not play, two others are available.

Windows Media Player

Windows Media Player problems can be corrected by either downloading an updated WMP from http://www.microsoft.com/windowsmedia, or in extreme cases un-installing WMP and re-installing.
