Fast Internet Connection Required to View Course Videos
Most cable and DSL connections should be more than adequate to watch CDI training videos.
However, if you feel that the videos are slow to load, turn off any background applications that could be using up bandwidth. Also if you have multiple sessions open within your browser, close them.
What is buffering?
Buffering is a way of preloading the videos you are viewing so that delays caused by your Internet connection don't cause the video to appear choppy.
When you play a video, a light gray bar will appear near the bottom of the video, showing you how much of your video has been buffered.
Your playback should be smooth as long as you're viewing your video within the light gray buffer region.
If you're experiencing choppy playback, pause the video, allow the video to buffer for a few moments, then try playing your video again.
Check your Internet speed
and click BEGIN TEST.
Make sure your Internet usage isn't at full capacity -- for example, someone at your location is not downloading a large file while you're trying to watch the course.
Check your computer for viruses, spyware or ensure that your hard drive is not full.
You can try moving your router to a new location to improve signal strength.
Your router should be elevated off the floor (for example on a bookshelf or desk) and placed in a central location.
Move any cordless phones, microwave ovens, or other wireless devices away from your router. These devices often cause wireless interference.
