ExBlend() was not intended for this source but I thought I would give it a try with
Didée's Blur and TDecimate. The script below produces less blending with ExBlend
but does produce noisier fixed frames, you might want to give it a whirl.
I did not play with args to FixBlendIVTC nor TDecimate.

Import("D:\avs\FixBlendIVTC_v091a.avs")
Avisource("D:\avs\problem video.avi")
A=blur(0,1).FixBlendIVTC().TDecimate()
B=blur(0,1).Exblend(PAL=0,show=0).Tdecimate()      # EDIT: Added PAL=0
StackVertical(A,B)
ConvertToRGB32()	# VDUBMOD dont like 636 Width Planar

EDIT: ExBlend() does no postprocessing on recovered frames, the intended source usually does not need any.

EDIT: The below script just shows a 4 window clip, original unblurred frame Top left,
Blurred only frame Bot left, FixBlendIVTC top right, and ExBlend Bottom Right, its
probably not exactly frame for frame (TDecimate) but it is good to see all four clips at once.
In the Exblend() clip, the dog has a more consistent number of legs.
All clips have had TDecimate() applied.

Import("D:\avs\FixBlendIVTC_v091a.avs")
Avisource("D:\avs\problem video.avi")
A=blur(0,1).FixBlendIVTC().TDecimate()
B=blur(0,1).Exblend(PAL=0,show=0).Tdecimate()      # EDIT: Added PAL=0
Z=TDecimate()
X=Z.Blur(0,1)
L=StackVertical(Z,X)
R=StackVertical(A,B)
StackHorizontal(L,R)
