Another observation - if I grab (xwd) a frame produced by mplayer +
ilpack then it looks better than the both the interlaced in my
screenshot - it's as good as the best looking (progressive + flags) one
without the chroma field bleed of course.

mplayer -vf ilpack,scale -noaspect -vo gl ~/snooker-short.ts

I have to use gl as 422 vdpau is broken on my gpu (radeonsi)

Forcing ilpack into dumb (unweighted filter) mode - ilpack=0 produces
the banding/misaligned chroma similar to what's seen on ffmpegs worse
output.
