That was one of the exact frames I noticed, but did you take a look at the separatefields() first? (frames 1728&1729.) The original is trashed on that frame. There's not much you can do when the source has such nasty artifacts... unless it was a rip error, not original encoding error.

Throw some post-processing after it, which is a good idea for low-bitrate anime anyway. My first inclination is fft3dfilter & degrainmedian - which are good for combing and ringing, without purging details - unless you want to try the anime-specific filters in mipsmooth, tbilateral, or msmooth for stronger removal. Add one of Dideé's sharpen filters and you have your very own remastered anime!

Here's what I used to good effect:

fft3dfilter(plane=4,sigma=4,sigma2=1.5,sigma3=0,sigma4=0)
degrainmedian(limitY=2,limitUV=4,mode=3)
LimitedSharpenFaster()
