So yeah, i find two DVDs with incorrect levels. So i used Levels filter manually set "out min/max set to 0-255" or Range Conversion. Both produced the same result. So Range Conversion seems works.
Levels filter have advantage - it could be placed to any order and applied after filters. So filters may be applied to uncorrected "dull" source video and may produce better quality.
Also in x264 settings i manually force set to VUI ot "tv".
Still not sure about DAA and other AA filters. As you noticed they improve aliased parts of the image but same time may smooth and soften other fine lines that are not real aliasing. Will test more how DAA behave when applied after resize...
"Color - Tweak Chroma 0 Why not use it as first filter instead of last?"
I don/t know really. Thought maybe filters may work better with color pixels data instead of pure greyscale. But maybe not. Need to test it...
