I just got these today…
Star Wars Unknown date Sky Movies
The Empire Strikes Back Premiere 25th Dec 1988 HTV West
Return Of The Jedi Premiere 26th Dec 1989

Sadly the star wars VHS got caught in my VCR, so the opening crawl has tracking issues. I’m scared to rewind the tape to the start now. Also there seems top have been a technical fault during the broadcast as the screen cuts to the sky movies logo for a few secs just before they escape the death star.

The other two tapes work fine and they include commercials (well I only checked up to the first set).
