Video Error - Scripting Help

Yo

Ok, so I'm ripping Excel Saga at the moment which I discovered has HORRIBLE interlacing. After entering the telecide order of zero in my avisynth scripts that problem got solved.

Problem is I noticed something else, now around all the edges of the lines, there is a fuzzy sort of pixelation (it moves around so it's irritatingly obvious when in motion). I'm not sure what it is so I don't know an appropriate line to add to my avisynth scripts. Anyone have an idea? Below is a cap of some random shot that has that problem in it.

The footage isn't perfect because I had to save it as a jpg for file size sake instead of uploading a bmp. The grains are in more than the palces I highlighted, I just pointed out a few for simplicity's sake.

That looks like dot crawl. I'd suggest TComb, only for the fact I could never figure out how GuavaComb was supposed to work.

Oh yeah, forgot to mention. Dot crawl removal is supposed to be done before the IVTC or whatnot.

Ok, this has me a bit lost:

Do I just put this in my script

tcomb(mode=0,fthreshL=255,othreshL=255) (adjusting the values of 255 as according to the help me file)

Or is there something I have to do with these other files in the zip? Using that script is easy enough to understand but there are a ton more files in the zip that I don't understand what to do with.

Yeah, I guess. I've not used the filter very extensively (just on the R1 of End Of Eva and I tried using it on the Rayearth OVA, but gave up), but that's what's recommended.

In the 'src' folder I assume. That's just the filter's source code; you only need that if you want to compile it yourself.

GuavaComb only works on static scenes, so that might explain any lack of functionality you were seeing...

Actually it was more that I couldn't figure out how to configure the options. It was a long time ago, right as I was learning AviSynth (early 2004, I think). Thankfully not too much of the footage I've worked with exhibits dot crawl, or at least I didn't pay much notice to it until about a year ago when I had to look for something to clean up a little piece of South Park footage and still couldn't figure out GuavaComb. Unfortunately, I didn't know about TComb (if it even existed at that point in time, that is). I wasn't really aware of the particular aim of GuavaComb either; I would have just taken anything that said it would correct dot crawl and tried using it.
