I have the widscreen vhs set and i always figured Jedi was the same as the JSC because its misframed high up on the tv set when played back.
Every widescreen copy on home video that was legit before the definitive or faces of Jedi was misframed. The first version in CLV that was fixed was the 1995 faces, and of course you got the 1993 CAV release in the def box.
