When you stream a movie on Netflix, either the DRM doesn't work, or you no longer have unrestricted access - from inside the computer - to the pixels on the screen, or the audio being output. i.e. If you try to screenshot the movie, or redirect the audio into a file, you won't be allowed. The video and audio quality may be downgraded if you attach non-HDCP (a DRM system for local video and audio) outputs to your laptop. Sometimes Netflix will simply refuse to stream anything if it isn't sure that the path from the video decoder to the monitor's screen is secure. e.g. https://www.reddit.com/r/apple/comments/3j0vck/whats_hdcp_and_why_cant_i_play_netflix_on_my/ https://www.reddit.com/r/apple/comments/3j0vck/whats_hdcp_an... You don't have permission from Netflix to prevent this. If you're in the US or UK - and many other jurisdictions - it is illegal for you to do so, even if it's very clearly within your fair use (or equivalent) rights. In the future, it's likely that DRM will extended to add and detect watermarks to restricted video and audio output, requiring you (and those around you) to cede full use of any other devices with microphones and cameras that might happen to capture that output.
