reinterpolate420 - eliminate chroma jaggyness of PAL-DV

[abraxxa]

I tried your plugin Wilbert but it doesn't really help.
The video looks like pixel-doubled after inserting 'ConvertToYUY2(interlaced=true)' (what is needed because DirectShowSource gives me YV12).
The source is PAL DV interlaced BUT edited with Adobe Premiere by a friend (who isn't very experienced with video codecs...).

This is my avisynth script:

loadplugin("C:\Programme\AviSynth 2.5\plugins\kerneldeint140.dll")
DirectShowSource("E:\DVDRIP\TSC_DVD_#1\gtech3-raw-big.avi")
ConvertToYUY2(interlaced=true)
#ReInterpolate420(interlaced=true)
KernelDeint(order=0,threshold=6,sharp=true,map=false

Any suggestions?
I search the whole doom9 forum and tried out different things for hours but I just don't get the quality of your screenshots
