<<The defence of "for study" isn't nearly enough for the copying of the entire episode for someone else to use.>>
Actually untrue. I'm not saying legal (yet) you seem to have the knowledge base there. But here's a REAL LIFE example -- presented as a hypothetical, to keep the names at bay.
One of the teachers in a renowned musical theatre workshop (e.g. a class whose mandate is to train and nurture musical dramatists) moderates a Master Class several times a year. This class is different from the regular classes in that an invited panel of two "star" writers sits in. Two projects-in-progress each give a 30 minute presentation for criticism and comment by the visiting dignitaries. The moderator guides the discussion, but the invited panel's response is the focus.
In anticipation of each Master Class, the moderator wants to try having the Masters as prepared as possible to assess the material. In the case of, say, a developing musical based on a film, they might comment on the effectiveness of the adaptation. To that end, though, they need to know the film. The moderator sees to it that two copies of the film are dubbed (from an original copy, purchased or rented) and sent to the master panelists, so they can view it prior to the class, the better to discuss the project comprehensively.
Legal? Based on what you've already said and specified, likely not. But a legitimate educational basis for necessarily needing the ENTIRE film ... absolutely. No?
(Administrator: many apologies for veering off Tintin topic here. I won't make it a habit, and if it wants to go on further, I'll ask if my esteemed correspondent has any desire to move it offline with me. Each new beat of this thing is just so interesting, is all ...)
