I have the Phantom 3 Standard and I am having problems playing back the videos.  I have the default windows movie player and have used VLC media player and I just get an error.  It appears only RealPlayer works, but the video is choppy.  Any suggestions?

Have you tried to play the videos in other computers ? Are the videos you recorded are 2.7K ?  Some computers may not be able to play videos with such high resolution .

Simply put, if VLC Player does not deal with it, your computer is just not up to the job.
