The output of mencoder encoding with -ofps 20 clearly shows it's
properly dropping a single frame at a time no more than one every 10th
of a second, not multiple once as you believe.  

Playing back your encoded file, I don't see any problems at all. 
Converting from 25 to 20 fps will never be pefect, but it looks as good
as it possibly could, an plays quite smooth, both foreground and
background objects.

And when you want to post a reply, you should click "reply" not compose
a new e-mail with a similar subject.  If you are unable to do so for
some reason, you can respond via gmane instead.  And CCing people
on a mailing list so that they get 2 copies is just irritating.
