I'm not trying to deinterlace them, I want to keep them interlaced

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.

Because a field blend deinterlacing filter is a "destructive" deinterlacer, intended for deinterlacing video that is truly interlaced - such as camcorder footage.

This is not true. If PAL is progressive already why can it be deinterlaced? Deinterlacing means making it progressive. PAL can be interlaced or progressive. I have lots of PAL interlaced dvds. Almost every camcorder films interlaced.
OK, captures from TV or a camcorder - i.e. from a video source - will be truly interlaced. If you want to deinterlace, e.g. for viewing on a PC, you must use a destructive deinterlacing filter on it.

However, PAL video from a film source is created with 2:2 pulldown - that it, the first two fields come from the first frame, the next 2 from the second, and so on. Assuming the capture card is working correctly, every 2 fields should make the original full frame in your AVI.

On the odd occasion when something is not working correctly, to de-interlace a PAL film-sourced capture you should use a non-destructive deinterlacing filter such as this one. Basically you can consider this as IVTC for PAL.

Is there a program that can test if an avi is interlaced or progressive
Yup, it's called virtualdub. Load the file, and examine frames with motion. If you see combing, then the video is interlaced.

Citizen and Moth3r thank you very much for showing me the light!
I admit it, I was dead wrong.

This is kind of strange. When I encode "bottom field first", uncheck "progressive frame" and check "alternate" there seems to be a lot less dotcrawl if I encode "top field first", check "progressive frame" and check "zigzag". When the avi is encoded as interlaced it seems to play more smooth without any loss of sharpness.
