I changed my mind. I ordered it because I think it'll be a good chance to expand my experience, maybe this problem is not very common.
Buy this thing is not very difficult for me because I live in Japan:p (although I'm not japanese, I'm an abroad student in Japan)

The Anime's name is "Gunslinger Girl Blu-Ray Box".

And I make some research in YUV sequence since I found a YUV viewer, strangely the problem is only found in V plane but not U plane.

So the problem is like this:
Y and U plane is pulled-down properly but V plane not, I want to IVTC each plane separately, any suggestions?

See UToY(clip) (http://avisynth.org/mediawiki/UToY)

Very thanks, now I have Y U V three planes, but how can I join them together?
isn't that MergeChroma() can only handle whole chroma planes?

On the page you were linked to, there is also the explanation for YtoUV(). Sloppy reading on your side, eventually? ;)

Y = clp.greyscale()
U = clp.UtoY()
V = clp.VtoY()

Yx = Y.process()
Ux = U.process()
Vx = V.process()

result = YtoUV(Ux,Vx,Yx)

Very Very thanks...
until now, I can't understand (clip) exactly...
following your explain, now I can understand (clip) more clearly.

Thanks a lot.

now the only problem left is how to IVTC this damn clip:p

Why they don't do with more care in mastering process?!
