Today I sat down and wrote another IVTC filter, UnComb.dll.
This is for Avisynth 2.5+ YV12 only. It's fast, but not very smart, so use it only on non-problem material. I'll just post an excerpt from the readme file below.
As always, feedback appreciated.

********** from Readme_UnComb.txt **************
UnComb is a simple IVTC filter for matching up even and odd fields of properly telecined NTSC or PAL film source video. Think of it as a poor mans little brother to Telecide(). It is fast but that's because it makes no attempt at finding frames that must be deinterlaced.
USAGE - To use it just:
1) Place the UnComb.dll in a directory somewhere. If that is the C:\ProgramFiles\AviSynth 2.5\plugins folder (recommended) then you can omit the LoadPlugin command in your script. You can get UnComb from:
www.trbarry.com/UnComb.zip
2) In your Avisynth file use commands similar to
LoadPlugin("F:\UnComb\UnComb.dll")
Avisource("D:\wherever\myfile.avi")
UnComb()
Of course replace the file and directory names with your own. There are no parameters.
KNOWN ISSUES AND LIMITATIONS
1) Requires Avisynth 2.5 and YV12 input.
2) Sorry, currently requires a P-III, Athlon, or higher. Needs SSEMMX support.
3) It will not handle improperly telecined material or bad video edit. It does not even check for combed frames. It just makes the best field match from what is available. It will not blend, interpolate, deinterlace, or even care. It is for reasonably good source material.
4) It does not and likely will not have fancy options like Telecide(). Use Telecide() when needed.
5) It does not decimate. Follow UnComb with Decimate(5) when you need to decimate frames from 30 to 24 fps.
6) It is wicked fast. ;-)
