When watching a movie the movie is constantly stopping to download. Why is this happening

If there is an interruption to BB signal; this might happen.

You cannot download movies to your Vizio streaming device. Do you download the moves you watch on TV ? Of course not. A TV allows you to watch movies, shows, etc.BROADCAST OVER THE AIRWAVES OR CABLE. Similarly, a streaming device allows you to watch movie, shows, etc. STREAMED/TRANSMITTED OVER THE INTERNET. So, if you can watch Netflix trailers on your Vizio, you can watch Netflix movies (but not download them). Select a Netflix movie, press Play on your remote and see what happens.

• 1 Allow the movie to load completely, or at least halfway, before you start to watch it to stop video buffering.
  
• 2 Start the movie and then hit stop until the movie has fully or halfway loaded. As the movie is loading, you should see a yellow or gray line. The line you see will get longer as it loads.
  
• 3 Close all windows that you don't need. Having too many windows open will slow the loading process.
  
• 4 Resume play once the movie is at least halfway loaded or fully loaded. By this time, you should be able to enjoy the movie without the video buffering or constant starting and stopping.
  

You have to uninstall it in the program files.

If you are watching online video this is normal for a slow internet connection. Live streaming needs alot of bandwidth. Its not your laptop.

Is it ok with a DVD movie or downloaded movie??
