This is one of the problems as you need to present both fields to the 
deinterlacer so that it does a good job without doing funny slomo effects.

This is why (I assume) both fields are handled in the show section of AVsync

If the avg estimation of avsync is smoother, things would be better. just 
need a fast attack on start/seek.
say varying TC filter with a max of N which could be any number.

also Davin, still thinking on how I can expand on my previous arguments to 
make them more compelling.
this subject has been on my backburner for quite a while.
