The technidisc for Jedi would most likely still have the picture missframed because all released before the definitive collection were that way.
I suppose someone who owns it can check to see if the picture is not corrected.
Moth3r as far as i know the japan special collection for star wars does not have the incredible shrinking ratio problem, but i could be wrong.
If it is not screwed up like the US pressing you could buy a copy of the japan laserdisc, if you don't mind the picture being shifted way up in the frame and burnt in subtitles. Also is in CAV format and not CLV.
