No luck.  This is the command I am using.  I swapped out kerndeint for
yadif according to your suggestions:

mencoder "$infile" -ovc x264 -aspect 16:9 -vf
harddup,kerndeint,scale=-10:-1 -x264encopts
-nosound -of rawvideo -o "$file.h264"
mencoder "$infile" -ovc x264 -aspect 16:9 -vf
harddup,kerndeint,scale=-10:-1 -x264encopts
-nosound -of rawvideo -o "$file.h264"

using yadif=1 and 50 fps makes the final video 'shudder' along.  It is
smoother (but half speed) if I remove the two 50 fps commands.  There is
still a green band at the bottom of the film even when using mcdeint
with yadif=1.  I tried all combinations of yadif 0/1 with/without
mcdeint and 50fps to see if anything worked, but they all show a green
band about 10 scan lines thick.  I can post a screenshot if you want,
but what is the best way to do that on this mailing list?
