I recently saw a two-hour movie of COLUMBO called, "One Note Too Many" about a film composer who murders a protege during one of his sessions. Is this available on video? Also, there is another movie-related episode which I believe co-stars either Robert Conrad or Robert Culp, in which a filmmaker inserts subliminal frames into showings of a film in order to be able to murder someone. Anyone know the name of this episode and whether or not it is on video? Thanks for any help.
