Chromashift before or after denoising

[25FPSBB]

Question for the experts. Is it better to use chromashift before or after denoising? In my scripts, after i use QTGMC lossless (without sharpening, sharp=0.0), I usually use TemporalDegrain2 with postFFT=1 and set the sigma afterwards. After that, I adjust chromashift and do sharpness with LSFmod. My problem is that the left edges are 99% perfect in the image, but the right edges often have a very slight halo or still a tiny bit of chromableeding. There used to be a filter called FixVHSOversharp that you could use for the right or left side but it works only in Avisynth not Avisynth+. I know there is DeHalo_Alpha but i only use DeHalo_Alpha in an emergency because it usually destroys too many details in the image. Is there an alternative to FixVHSOversharp, or is it my fault that I shift the chroma at the wrong time. My captures are most from old retail VHS PAL widescreen movies and the target is to get a anamorphic widescreen DVD.

Here is the script i use most of the time and i tweak the settings to the capture i have done:

Avisource()
KillAudio()
AssumeTFF()
QTGMC(Preset="slow",SourceMatch=3,lossless=2,MatchPreset="slow",MatchPreset2="slow",TR1=2,TR2=1,NoiseTR=2,Sharpness=0.0,EdiThreads=4)
SelectEven()
Crop()
ConvertToYV12
TemporalDegrain2(degrainTR=1,grainLevel=1,postFFT=1,postsigma=2.0,postsigmaC=2.0,fftThreads=4)
ChromashiftSP()
LSFmod(Strength=60,Smode=5,ss_x=1.5,ss_y=1.5)
AddBoarders()
ConvertToYUY2()
Splin36Resize()
Prefetch()

I know you want samples of my raw Capture and my encode. But i think there is no need for it because this problem is in most of my encodes. And i set the Chromashift on different places already to test it out but i can't get it perfect. For capturing i use a Phillips or JVC or Sharp VCR with TBC or a Panasonic without TBC ( belongs of the tape) passthrough Panasonic ES10 or ES60 or a electronic Design TBC to my Hauppauge LiveUSB for PAL/ Secam or Diamond 500 for NTSC. I capture with Lagarith or Huffyuv in Virtualdub or AmarecTV. And i use Histogram in Virtualdub to avoid black - white crush. My results are very good and sometimes they look like commercial DVD's but to get it perfect i want to kill this last small error.
