No problem!

You can see the effect on the edge of the roof of the halls in the background.
Is this a deinterlacing problem OR a choma problem?
Try it with this avisynth script:
loadplugin("c:\Install\Video\AviSynth\KernelDeint_1.5.2\kerneldeint.dll")
AviSource("c:\temp\gtech3_snip.avi", false, "YUY2", fourCC="CDVC")
KernelDeint(order=0,threshold=5,sharp=true,map=false)
I tried also with order=1 but that doesn't help either...
