Need help with problematic interlaced source

[MetalPhreak]

I need some help with the provided sample below; It's from a R2 NTSC DVD but I can not for the life of me get this to look decent - there is field blending in the source and a normal deinterlace looks very bad with all the blending. Is there any hope for this source or should I just give up on getting it to look decent?

CDeInt seems to be getting good results with the interlacing / fieldblending removal, although it doesn't seem smooth or stable.

FFmpegSource2("VTS_01_1.demuxed.m2v")
AssumeTFF
o = GetParity ? 1 : 0
a = LeakKernelBob(Order=o, Sharp=true, TwoWay=true, Threshold=7)
DeInt = CDeInt(Bob=a, BMode=2, NLV=0)
TFM(Order=-1, Mode=0, CThresh=6, MI=64, Display=false, MChroma=true, Slow=2, PP=2, Clip2=DeInt)
FDecimate(Rate=24000.0/1001.0, Threshold=1.0, Metrics=false)

I tried it with your script, it does get rid of most of blending but on fades it's definitely not smooth. You can see the fade start and then step back a frame and then continues.
For example if the fade should go: "a, b, c, d, e" it instead goes: "a, b, a, c, d, e" or "a, b, d, c, e"

Edit:
After playing around with your script it seems FDecimate was causing the problems during fades. Just using TDecimate instead improved it.

Try:

Yadif(Mode=1)#or a better bobber, one such as QTGMC
SRestore(Frate=23.976)

...there is field blending in the source and a normal deinterlace looks very bad with all the blending.
Not sure why you'd even try deinterlacing it since you recognized the field-blending right off the bat.

Thanks for the suggestion manono. I'll try that tomorrow when I have some time.

Edit:
After looking at some samples I found one where neither of the above methods work that well, both look better than what I was doing but I don't think the result could be called good. Here's the sample:

I would appreciate if someone could have a look at it and give me some advice on it.
