Another cheap way to get movies in the late 80s/early 90s was to pick up a CED player and go find some CED discs. After they axed the system in 1986, the discs and players could be had for a song. My dad bought a CED player around 1984, but after production stopped, he was able to score a whole stack of discs. The discs would skip, though, and you had to replace the stylus every so often. I have no idea if you could still find a stylus for those things or not, and the discs are really fragile, so unless they're very well-cared-for, they're most likely unplayable anyway.
