How to use Android native video player instead of unity player

I have a situation where I am trying to play a fullscreen video on my mobile app and it keeps crashing on my android device. It's running Android 4.4 and I suspect the issue is the built in Unity player so I would like to force the app to use the Android native player for testing purposes. I don't have any other devices running 4.4 so I don't know if it's a device or OS issue.

Here's the code:

  if (fullScreen && (Application.platform == RuntimePlatform.Android))
   {
       if (mFilename == null)
        {
            return false;
        }
         Handheld.PlayFullScreenMovie(mFullScreenFilename, Color.black, FullScreenMovieControlMode.Full, FullScreenMovieScalingMode.AspectFit);
         return true;
  }
 else
 {
     return videoPlayerPlay(fullScreen, seekPosition);
 }

I'm using Unity 4.3.1f1.

The phone is a Nexus 5 running Android 4.4 .
