Most of Netflix's features are visible, but there is a secret set of options that you can access while streaming. By pressing Shift-Alt-Left Click, a small window appears on top of the stream including a few statistics. But the option we're interested in is the Stream Manager. Here you can see the current bandwidth usage used both in playing and buffering the stream. If you're having issues with a long wait due to buffering, the Stream Manager lets you manually change the bandwidth rate to suit your Internet connection.
