What should I do if my video will not play?

There are many things that can affect the quality of your video so we have put together these instructions to help you review all the things that need to be tested in order to trouble-shoot video quality.

The first thing we want to assure you is that we have done everything possible to make sure that our videos will play well.  Our videos are hosted in the cloud by Akamai.  Akamai has servers around the world to make sure that your videos are sent from the server that is closest to you.  By hosting our videos with Akamai we make sure that you receive the highest video quality. If you are experiencing video buffering or freezing at home or at the office there are a number of things you can do to help us troubleshoot.

  • Buffering: We provide you with three (3) speed choices that you can select when watching a video.  If the video is buffering then the first thing you want to click on a slower speed option found at the bottom of the video window. Try clicking on Medium and Low and see if that allows the video to play without buffering. If it does not, please read through the rest of this FAQ and follow the steps outlined below.
  • Video will not play: In order to play our videos, you have to have Adobe Flash Player installed. If you click on the video and nothing happens, then you do not have Adobe Flash Player installed.  Click on this link to download and install it.
    • If you have Adobe Flash Player installed and your video is not playing, complete the following steps:
      • Go to your course page, select a video, and click play.
      • Once the video begins playing, place your mouse over the video and right click.
      • You will see the several links and the last link has the words “About Adobe Flasher Player xx.xx.xx” (version # you have).
      • Click here , where you will see your version and what is the latest version. You need to have the latest version installed.
      • If you do not have Adobe Flash Player, click here to download and install it.
  • Popup Blockers: Please check to make sure that your pop-up blocker is turned off when you go to our website. This will prevent the video window from opening.
  • Your Connection Speed: Internet speed needs to be 2.0 Mbps upload and download to successfully watch the videos.  You will want to check and see if your connection speed is 2.0 Mbps or higher.  You can do this by clicking on this link and running a speed test.
  • Jitter and Packet Loss: Your Jitter rate lets us know if your connection speed is consistent while your Packet Loss rate lets us know if your internet connection could be losing pieces of the video.
    • Go to www.pingtest.net to determine if there is any Jitter or Packet Loss on your connection.
    • This is measured by a letter scale with A being the best.
      • If your Packet Loss is below a B, your connection is losing pieces of the video and causing the video to skip.
      • If your Jitter is below a B, your connection speed is very inconsistent and may be changing while you are watching the video which will result in buffering issues.
      • If either of these is the case you will need to contact your internet provider.
  • Ports: You will need to have ports 1935, 443 and 80 open. You can run a port test at this link.
    • If you are watching from work and those ports are not open, check with your IT department.
  • Shared Internet Connection: If you are on a shared internet connection, test playing videos during non-peak hours when usage by others on your network is low.
  • Reset Your Browser: If you've tried all the previous steps, your browser may be retaining data that needs to be deleted, and this requires a reset. If you are using Chrome, use the instructions in this link to reset your browser. If you are using Internet Explorer (IE) you may need to reset it. You can do this by clicking on the cog icon on the top right of your page. Then click on tools, internet options, advanced and reset. If you are using Firefox, use the instructions in this link to reset your browser.
  • Other things to check:
    • At home or at work, test using different browsers and computers to see if you get the same result.
      • Make sure you have the latest version of the browser you are using.
    • If you are using Internet Explorer (IE) you may need to reset it. You can do this by clicking on the cog icon on the top right of your page. Then click on tools, internet options, advanced and reset.
    • Try from a different location using a different network.
    • If you are on a wireless connection try a wired solution.
    • If you are on a home network:
      • Test playing the videos when you are the only user on the network.
      • Try by-passing your router to eliminate it as the point of failure. A direct plug from your ISP to your computer will take care of this and will make sure that neither your router nor other users are affecting your connection.
  • Make sure you do not have any other programs open. File sharing and peer to peer sharing programs, even when limited to low bandwidth, can make it almost impossible to stream properly.
