Video recordings
Notes-bibliography style: citing specific types of sources
Part II. Source Citation

If you viewed a live performance, a movie, or a television program or other broadcast source on a video recording, cite the recording. Like published works, such recordings generally have stable and available identifying information and should be listed in your bibliography.

Citations of video recordings generally follow the pattern for books, with the addition of the medium (VHS, DVD). Note that in the second example, the citation is to material original to the 2001 edition, so the original release date of the film is omitted.
