There is the 1993 Krieg der sterne trilogie silver screen collection, star wars, empire and jedi released individually and not as a set as i'm aware.
the french 1994 laserdisc letterbox pre-faces and pre- special edition I think it comes with from star wars to jedi.
( i have accuired this release but won't get it in the mail for a little while)
I think it's identical to the u.s. special letterbox set with hologram cover, but Funny enough in the u.s. it was not released on laserdisc. Maybe because the source material was released already as single double laserdisc releases, i.e. from the famous missframed japan releases.
The spain release is supposed to be of dubious quality but was'nt there something that set it apart from the rest like narration or something?
