There seems to be since v1.05 a bug lingering in resize routine of
AVIsynth. When resizing in RGB colour space (bilinear or
bicubic) the first column of the frame gets wrapped around and
mixed into the last column of the resized frame.

Open the
script below in Virtual Dub and examine the right border of the
frame
(choose preferably a source where left and right borders
are different.

source =
AVIsource(".\BW.avi")
YUVrez1 =
Source.BicubicResize(70,50,0,0.6).ConvertToRGB()
RGBrez1
=
Source.ConvertToRGB().BicubicResize(70,50,0,0.6)
StackVertical(RGBrez1,YUVrez1)

    Fixed in CVS, but needs heavy testing.
