Hue, saturation, CMYK etc...

I'm currently working on 1 video and i have 2 sources: dvd, vhs both are retail. Assuming the dvd source has been well transfered (and i think it has), how can i make the vhs one look like the dvd one ?

Thus far i tried with virtualdub's filter, color mill & gradation curves, to not cite 'em, but it seems extremely difficult.I'd need some expert advice.

Also, what i would like to know is if there is a tool to analyse the picture in the first place, this has to be precise work.

The pics:

Note:
DVD: mpeg2 (VOB)
VHS: Avi (HUFF)

Ok Colourlike is not bad but i wanna use a more traditional method if that's possible because i have many tapes and not all of them in DVD so colourlike would be useless in lots of my projects.

You can do this easily with SmoothCurve:

*Click the image to enlarge*

Code:

str=8
thr=32

SmoothCurve(Ucurve="0-0;"+string(128-2*thr)+"-"+string(128-2*thr)+";"+string(128-thr)+"-"+string(128-thr+str)+";128-128;"+string(128+thr)+"-"+string(128+thr-str)+";"+string(128+2*thr)+"-"+string(128+2*thr)+";255-255"\
           ,Vcurve="0-0;"+string(128-2*thr)+"-"+string(128-2*thr)+";"+string(128-thr)+"-"+string(128-thr-str)+";128-128;"+string(128+thr)+"-"+string(128+thr+str)+";"+string(128+2*thr)+"-"+string(128+2*thr)+";255-255")

Adjust str & thr to your taste

Where can i get this filter ? i can't find an official thread

Edit:
I have downloaded SmoothAdjust v1.62 but i don't understand, there are 6 .dll inside. I'll try with SmoothAdjust-ICC-x86.dll hopefully it work with Xp 32 bits

The problem is i tried your settings and they have no effect as far as i can tell
