That is a funny source. 
When treating it as 'progressive' one clearly sees the lines.
If you treat it as interlaced and throw away half of the frames, you get one b&w and one colored frame.
This is confirmed if you separate the fields, you see that one field has color the other not.
So my guess it's either the source itself or some compatibility with the DV codec used for this.
If you also got a 64bit vfw version of the dv codec, that was used to capture this, installed on you system, try what happens if you enable "Filtering->Vapoursynth->Misc->Source->Prefer AviSource for .avi input".
