I can't figure out why MC_Spuds (http://avisynth.org/mediawiki/MC_Spuds), TemporalDegrain_ChromaMod (http://avisynth.org/mediawiki/Temporal_Degrain) and a few other denoisers are causing visual artifacts on my Invader Zim NTSC-DVDs. Any helpful input would be great, thanks.

VOBs:
The sample (http://www.mediafire.com/?y4im3x431udg9hj) that has problems with the aforementioned denoisers.
A sample (http://www.mediafire.com/?z9c1y700eiw7xtl) with the kind of noise that I was trying to get rid of.

Script:
SetMTMode(5, 2)
DGDecode_mpeg2source("D:\My Videos\VOB\ZIM_VOL1\ZIM_VOL1.Title4.d2v")
AnimeIVTC(mode=1, killcomb=1)
SetMTMode(2)
MC_Spuds()
#TemporalDegrain_ChromaMod()


The following are also causing visual artifacts:

MDegrain1/2/3/4

The second is a good example of temporal averaging gone wrong. Not sure what's happening with the first without seeing the source in motion.

have you tried to use those filters without MT?

First off, I have to ask, why in the world do you want to denoise it? It's already as clean as hell.

The first one probably is as well.

Yup, made no difference at all.

The majority 'is' clean, but there are a few sections that suffer from compression artifacts; highlighted in the second VOB sample that I posted.
