Video Playback Problems

Why does the video stop playing sometimes?

In order to speed up web browsing, web browsers are designed to download web pages and store them locally on your computer's hard drive in an area called "cache". The cache contains a kind of travel record of the items you have seen, heard, or downloaded from the Web, including images, sounds, Web pages, even cookies. Typically these items are stored in the Temporary Internet Files folder.

When you visit the same page for a second time, the browser speeds up display time by loading the page locally from cache instead of downloading everything again. This sometimes results in less than current versions of web pages being displayed. When the cache fills up, performance can slow down and your hard drive may run out of space.

If your video stops playing before the video is supposed to end, there is a good chance that you have a corrupt temporary internet file that needs to be deleted. Once this file is deleted, your web browser will re-attempt to download the video file and you will be able to finish watching your video.

Before deleting your web browser cache, try refreshing the web page while your video is playing. To do a hard refresh on your web page:

  • Windows: control + F5  (or control + shift + r)
  • Macintosh: command + r  (or command + shift + r)

If you continue to experience problems, you will need to delete your browser's cache. Find your operating system and browser below for instructions.
