I just went back to basics as I was looking into why my patch didn't
get a sync 100% of the time. So I went back to bobdeint and it just
works - seemingly 100% of the time.

So the question is, why can't you use bobdeint with your modeline? I'm
guessing (because I've seen the same problem) that X is reporting a
slightly erroneous refresh rate (i.e. slightly too low) and hence bob
gets rejected.

A slightly cleaner way to do this would be to adapt a 2x onefield
filter - which would eliminate any osd flicker etc and might just
improve picture quality as there would be no bob adjustment or

Ah. The never ending joy of tinkering with mythtv!
