assistance in removing rainbow & weird color patches

[mahendra]

hi,
I am trying to convert a vob to avi (xvid) using virtualdub 1.9.9

can some one tell me what these color distortions are & how to remove them.
i.e., rainbow colors on the girls hair in the first screen
& weird purple color patches on the guys hand in screen the following screens & other color distortions too.

i work with virtualdub & filters, but never tried avisynth scripts,
just know that load the avisynth plugins in avisynth plugins folder & write an avs script & open the script with virtualdub.

so if the solution is with avisynth, i will need the script.

thanks in anticipation.
