This is resizing the chroma to 1/4 res then enlarging it to fit the full frame hoping rounding will get rid of some of the junk, right?
Yes, kind of. The output of the DV codecs replicates the chrominance over four adjacent pixels. Instead, it would be better to interpolate. But without my filter (which I think was actually written for VirtualDub) you can't fix those samples. The next best thing is to do the above.

Umm...actually. Now that I look at it, the 180x480 downscale should really be just decimation. Hmmm. Can you do that in AVISynth?
