GEN: Video Information

[Tawana West <twest@COMP.UARK.EDU>]

        Does anyone know where videos from the TV series
"Secret Life of Machines" or "Movie Magic" or any other video or video
series about machines and mechanical devices could be purchased?  My
husband is a
Mechanical Engineering professor and will be teaching a new freshman
engineering class this fall.  Could he videotape a program from TV
and use only a small portion of it for his class and still be within
"fair use" restrictions?
        Thanks for your help.
