What movie was it? There’s a good chance I can find it.
If you’re in Reddit, there’s also a subreddit dedicated specifically to this kind of thing (requests for stuff that is no longer available) called /r/DHExchange
I did some searching. I assume you mean “Relics: Einstein's Brain (1994)”? If so, it doesn’t look like it was ever released on anything but VHS, so I only found a TV recording and a VHS recording.
