According to the Agreement on Guidelines for Classroom Copying (http://www.copyright.gov/circs/circ21.pdf), single print copies of the following may be made for scholarly research or used in teaching or preparing to teach a class. Please note that these are minimum guidelines and that copyright law does not specify amounts that constitute fair use. What follows are guidelines only:

We recommend that you conduct a fair use analysis each time you plan to use a copyrighted work and retain records of your analysis.
What about playing music or videos in my class?
Section 110 of U.S. Copyright law clearly permits the use of lawfully obtained music and/or video in face-to-face classroom settings (typically referred to as performances or displays). The fair use case can also be made for changes to materials undertaken for purposes of commentary, criticism, or parody. We recommend that you conduct a fair use analysis each time you plan to use a copyrighted work and retain records of your analysis. A fair use case is generally eroded in cases where use is repeated.
Netflix allows for some Netflix original content to be shown during class using an individual subscriber's login for educational purposes. See their Educational Screenings of Documentaries section
Group performance (non-classroom setting, not educational use)
Please be aware that these exemptions for playing music and video in a classroom are unique to this teaching setting. If a performance (screening a film, playing music) is not a part of a class activity, but is part of a film series, concert series, etc. it is generally considered to be a public performance. In these cases, one generally needs to secure public performance rights. See the Seeking Permission tab for more information.
