Blending/improper conversion to PAL DVD?

[ShadowCircuit]

Hi everyone!
I've recently started learning how to use AviSynth with the idea to restore some of my DVDs.

At the moment, I'm facing a problem with a PAL (UK) copy of Yu-Gi-Oh! anime. After bobbing the video, it seems like the material is progressive because the resulting frames look identical (with some small up-down movement of the image). However, there seem to be some frames which are not proper progressive material. It seems to me that the fields of those frames are blended with the previous or next frames, resulting in visible lines if there is movement in the scene. I attached two photos as an example - the first one is a frame before applying bob filter, the second one is one of the fields after bobbing. I attached a (original) video sample containing those frames as well.

The frames in which the blending occurs seem to be distributed randomly, and my attempts to fix it with Srestore were unsuccessful. But as I said, I'm very new to this topic so I'm not sure if I'm doing something wrong.

If anyone has any suggestions how to fix this issue, I would be very grateful.
Thank you for your time!

something like:

h=Height()
BicubicResize(Width(), h/2)
TFM()
BicubicResize(Width(), h)

is probably, the best you can do,... (for upscaling, a better resizer could be used)
You still have the blends,..

Ps.: haven't looked whether one should use sRestore or something similar to get rid of some duplicates,... hmm,... maybe also try TFM().TDecimate(mode=7,rate=23.976) instead if just TFM().
