That s the standard reply by a Zen Master to a student who "conceptualizes" the notion that Buddhism is not "conceptual." If that is not what you meant and are just trying to make objective, historical assertions I m intrigued by where you might be getting that knowledge. The documents we have certainly do support that Sakyamuni taught a particular doctrine and that some people accepted his teachings and became his followers. On what basis would one support another understanding?
Remember that this is a part of the 8 precepts that need to be observed only by monks and those laypeople who may observe a particular day as special. For them it would interfere with the right concentration or mindfulness of the 8-fold path. In general there is nothing that stands in the way for Buddhist lay people to watch the theater, movies, or YouTube. :)
