Ah yes... I remember this video, there was several videos the Center for Traditional Orthodox Studies put out, or at least distributed back in the day from Etna, many were in Greek but a few like this one and some others that I wish I could find got translated into English. These videos were in VHS tapes (truly ancient indeed!) and were actually pretty commonly found ROCOR parishes back when ROCOR was in communion with the HSiR, these were common along with the "Orthodox Tradition" periodicals which are an invaluable resource, those along with the old St. Herman's Orthodox Word magazines are wonderful. I remember watching this documentary, along with another one that was popular among Orthodox Christians in the mid to late 90s that was produced by Sedevacantists (that also showed the WCC and such) on a VHS tape at a Ukrainian Church rather than a ROCOR one of all things! They had a big library and collection, and this happened to be in it.
