It states: "AviSynth uses a different interpolation as the one suggested by the mpeg2 specs (perhaps due to speed issues)."
Is there an AVS plug-in that does this properly, i.e., in accordance with the spec? Or is the difference so minor that it's not worth worrying about?
It looks like the AVS code is interpolating as if the chroma samples are midway between the luma samples on the y-axis.
