This is my Script:
# PLUGINS
LoadPlugin("D:\DGindex\DGDecode.dll")
LoadPlugin("D:\VirtualDubMod\plugins\Decomb521.dll")
LoadPLugin("D:\VirtualDubMod\plugins\SmoothHiQ.dll")
Loadplugin("d:\VirtualDubMod\plugins\aWarpsharp.dll")
# SOURCE
mpeg2source("D:\DVDVolume\VIDEO_TS\Hamtaro.d2v")
# TELECIDE
Telecide(order=1,guide=2)
awarpsharp()
crop(10,4,-10,-2)
LanczosResize(640,496)
Thanks for helping :D :D

That seems like ghosting to me, which sounds logical as your source is PAL. You are probably dealing with a crappy NTSC-->PAL conversion, so I suggest you to do a forum search for Restore24 and read up. If you have any further doubts don't hesitate to ask :).

aaah, threshold-ghosting. this is from a not-so-crappy standards conversion.
i've seen this on the re-mastered He-Man (don't ask) stuff. it's either a field-blend like chainmax said (you'll have noticed more artefacts than these in this case), or a hardware based method similar to restore24 - the only time these don't look like proper re-scanned film converted straight to PAL is when artefacts like the "kernelghosts" you're seeing show up.
as far as removing them... well, they'll only appear on single fields after largish motion, so perhaps something could be hacked together with removedirt fed with only the next frame (not the previous).
perhaps:
selectevery(1,1,0,1)
removedirt()
selectevery(3,1)
could help? i haven't tried this out (or even thought it through...), but it may possibly do something interesting, and may even help slightly :). i don't even know if my assumptions are right here...

I didn't really said that it was field blending. Like I stated before, I know nothing about blending (be it definition, detection or elimination thereof), but I read many times that restore24 was used for NTSC--->PAL conversions which is why I suggested it.

You could try my AWarpSharpDering (http://leak.no-ip.org/AviSynth/AWarpSharpDering/) function - if the artifacts aren't too bad it could work...
np: Kraftwerk - Nummern (Minimum-Maximum (Disc 2))

I was going to recommend a deringer/dehaloer, but then I noticed that he has a PAL source, so I assume these halos are not from EE but rather are byproducts of the standards conversion.

@baosen,
could you post a little bit of the source DVD? You just need to cut out a small section of the VOB (preferably something with lots of motion) and upload somewhere...

Well, my function doesn't really care where the artifacts came from, but you're right - thinking about it a bit longer, it won't do much, as most of the artifacts aren't along edges... :(
