Sony was able to get studios to release quite a lot on Video 8. There were even Disney titles. Two SoCal electronics stores I used to haunt back in the 90’s carried a bunch of them. It might have gone hand in hand with being an official Sony dealer. I can’t seem to find any domestic CBS/Fox titles on Ebay though. ROTJ would have come out well within the time frame of of Video 8 releases.
It can be tricky to search for Video 8 titles as a lot of Super 8 gear gets lumped into the results.

I briefly considered Video 8 titles as an alternate source for PCM tracks that can’t be found on Laserdisc, but Sony never seems to have made a 8mm deck with a digital out jack.
