I did not make this video, but the guy who did is like...one of the best people in the world. He explains everything in the video on what to do and why you should do this. I just did this myself (literally just this second) and like...HUUUGE increase in buffering times. If it doesn't work for you, dunno what to tell you, but it worked awesome for me! Just thought you guys would like to see this video, so ya.
