This is as expected and depends how your PC player decodes the video. With MPC-HC you have the choice:
For your hard-telecined source you will either see the 2:3 progressive sequence with the well known judder, or you see a sequence of 2 combed (interlaced) and 3 progressive frames.
The IVTC'd source is all progressive and basically judder-free with little remaining judder from the framerate (usually 23.976fps) and monitor refresh rate ratio not being an integer multiple.
For soft-telecined stuff it depends how the player handles the pulldown flags and outputs the fields on the 480i interface to your TV. The pulldown flags should be correct IMO for the samples which I provided.
As has been argued AVC soft-pulldown played via a BD player may only work for strict blu-ray compliant files, even burnt to a disc with the standard blu-ray structure rather than played from the USB stick in some container. I don't really know.

Film-source DVDs are normally scaled down from a 2K or 4K master (not counting early ones that used D-1 masters, which are 720x486). I wonder what type of scaling filter they use. I've been using Lanczos.

I don't know how studios do it, but as I understand, downscaling will always have to be preceeded by low-pass filtering (softening the picture) in order to prevent aliases.
