Almost correct. Shaw is there (but the scene is cut short) and the DS is from ROTJ. When I said "de-Paxis'ed", I was referring to the moon of Praxis in Star Trek which first gave us this effect.

Not on my version. Even if it did, that wouldn't be a problem because mine is in widescreen. I have the LD and DVD version (though I don't recall if the DVD version is anamorphic.)
