Colour differences, VirtualDubMod <=> Avisynth

[AsTimeGoesBy]

If i open the VOB file directly with VirtualDubMod the output frame doesn't look as the frame what is produced by AVI2DVD+Avisynth.

Sorry for posting two big screenshorts, but they would make it quite evident. If you would switch from one frame to the other, the 2nd image seems to be more green.

I haven't applied any filters both times. And here is my Avisynth script:
-------------------------
LoadPlugin("d:\programs\video\DgMpegDec\DGDecode.dll")
Mpeg2source("v:\_DVD_Kill-Bill\_NEW_vts_01.d2v")
crop(2,78,716,422)
bicubicresize(720,320,0.2,0.6)
-------------------------


Is that only an 'optical' color space matter caused by VirtualDubMod itself or where is the reason for that colour difference?

Thanks very much for the link!

Till now (hanging on my 3rd encoding with DGindex & Avisynth) i have thought the colour difference would only be occasionally an thus i have tried to eleminate it with Levels() and Tweak() command - with not much luck.

So I'm glad too see there exists a special filter to correct the colours. :)
