I think you're all leading yourselves on a wild goose chase. The poster clearly states he's describing a VHS cover, which are almost always different, radically different from the DVD covers. This is due to copyright issues with the cover artist.

So, unless you find a site that has an archive of old VHS covers, posting DVD covers is an exercise in futility.

It could also be To All A Good Night (1980).

The Gate - definitely The Gate

I think it is also Beyond the Darkness. It looks just like the sketch you posted.
