How can stop buffering while watching video?

What I do so that I don't get the interruptions related to buffering is I let the video load up a bit on its own before pressing "Play". I usually like to let the buffering loaded video be at least 2-3 minutes ahead of where I am before pressing "Play". If possible I let it load more than 5 minutes or all of it if it allows me to do so, before I press "Play".
