Were there any changes on this field in avs' chromaresample since then?

Also, does anyone by any chance know what method Sony Vegas uses when converting imported media to RGB in its own editing space?

I also have a bit similar problem with red shift, but of different origin, any idea how to combat it (crop by even values)? I've been told that upscaling by 1.25 factor causes this and there is no way to avoid it. Colorspace conversion does not happen (all being kept in YvV2).
