Royalties for use of teaching materials

Hi All; Perhaps some of you who have made instructional videos and
books, etc., would be able to answer this. Suppose I am teaching
privately and getting paid for it. I might decide to have my
student(s) view an instructional video or base a lesson on a chapter
in a book. If so, is the accepted and ethical practice to pay
royalties? If so, to whom: the author or the publisher? This would
not be a case of re-printing materials, students would probably buy
their own copies of printed work but the videos would be viewed and
discussed in class. Would it be better to simply have every student
purchase their own copy of the video? I don’t want to add any more
costs for the students than is necessary.

Thanks,
David L. Huffman
