This is interesting, because the first time ever I saw Star Wars might be the last time Pro7 showed the original versions. We actually recorded them on VHS. We also kept the corresponding TV Magazine article and it says “Nach zwei Jahren TV-Pause endlich wieder auf dem Bildschirm”. So according to your findings I guess it was 2000 then. The magazine article also talks about Episode I that already has been released in 1999, and they say this broadcast is not yet the Special Edition but the orginals.
