Show File->File information. Are you using any video filters? Is the output mod2?

I don't use any filter. What does mean mod2 ? I just push in a virtual dub video-compression- x264 codec and then file-save as avi.

The video is 511 pixels wide. Since you cannot divide 511 by 2 without remainder 511 is "not mod2". Add the "null transform" filter, select it and click "cropping" on the right side. Then set X1 or X2 offset to "1".

(Usually formats like H.264 use YV12 colorspace which needs to be mod2 width, mod2 height for progressive and mod4 height for interlaced content. http://avisynth.nl/index.php/Crop#Crop_restrictions)
