1. ACCESS A HIDDEN MENU TO KILL BUFFERING
If you find yourself infuriated by constant buffering, try this hack. If you're on a PC, press Shift + Alt + Left Mouse Click, and if you're using a Mac, press Shift + Option + Click. This will open Netflix's diagnostic menu.
From here, select the Stream Manager. This is the only place where you can manually adjust the buffering rate. By increasing the buffer rate, you can force Netflix to download much more video to your computer prior to showing the video.
You will have smoother, high quality video, and less pauses in-between for buffering, but you will have a longer wait before the video starts to play. By decreasing the buffer rate, you risk choppier, lower quality video - the video, however, will play much quicker.
