I remember the USA Network and SciFi Channel airings pretty vividly as well. They were also some of my earliest exposures to the films (I turned 9 in June of '94).
I still remember the bumpers at the end of the USA commercial breaks. It would just be several seconds of footage from a scene with the announcer guy going "we now return to" whichever movie. When they came back from the final commercial break for Jedi, the announcer guy would add "and may the force be with you."
For the letterboxed SciFi Channel airings, I still remember how the bumpers for Empire's commercial breaks would be Billy Dee Williams walking out into a room filled with the miniatures from the movies (iirc) and sharing bits of trivia like how the Executor model had however many thousand light panels. I distinctly remember he pronounced it like you pronounce "execute" and not "executive." They did something similar with Takei and Koenig for the Trek movies, which is how I first heard the story about the Starfleet Academy movie that never was.
