There is an online seminar that is being given on Shabbos by a Jew. The recording is being made available for those that can't make it on Shabbos. What do the sources have to say about a Jew buying the recording of the seminar (after shabbos)?
(In case more detail helps, the jew is giving the seminar over zoom and making a recording of it himself. I would also be curious if the answer differs if non-jews were making the recording.)
