But that's what we've been trying to tell you from the start, the PAL SW films are only interlaced on the laserdiscs, when you capture the footage the film returns back to 25fps PROGRESSIVE!
If you're trying to preserve the what you perceive to be interlaced footage then you'd scale the two fields of the frame separately, which as you discovered when you tried to rescale the NTSC 3:2 pulldown capture to anamorphic without removing the 3:2 pulldown, the resulting footage looks terrible.
