I doubt that. Home video recording, while a new thing in 1981, was not substantially different from making personal mixtapes on tape from radio or vinyl records which had been popular for decades. My grandfather had dozens of 4 track mixtape reels he made in the 60s. You could even go further back and say it wasn't any different than taking a photo of artwork for personal use. You didn't have to be that young in 1981 to understand what home video recording is.
