This is a total stab in the dark. I had a vhs when I was younger, in a blue cardboard box, not the plastic ones...the cartoons on there, which weren't too long, were VERY old...easily earlier than 1940s. I know there was either a Popeye cartoon on THAT video, or one of the same make. The picture and sound quality was awful which made it so much better. I remember on one cartoon there was some kind of genie...part of it is in a cave and part of that caves in...? I'm sure they weren't in colour either, or just a dirty black and white.
I know its highly unlikely I'd find anything with such little info, but its worth a try.
