"Meeting at Midnight"/"Black Magic" is not currently a PD film which accounts for the lack of many budget releases of this title.
In fact there is some doubt that it ever was PD which may be the reason that any of the earlier releases you referred to have gotten pulled. Any such releases must have had limited distribution as I don't recall ever seeing any of those in my area. In those early days of VHS all I ever bought were public domain titles as that was all I could afford. I have some not so fond memories of having to pay six or seven dollars just for a blank tape which would be reused over and over again.
