Thanks very much for your reply. When I tried your command line, my results
were very similar to the results I had been getting with pullup,softskip:  a
pattern of 3 unique frames followed by 2 similar frames. This seems very odd
to me, the invoked filters being so different.  I mean how could those
completely different command lines yield such similar output unless neither
method was having any effect?

Could it be that something else in the command line is interfering? Here are
my precise command lines for each method.

pullup

mencoder -oac copy -ovc lavc -lavcopts vcodec=mpeg2video:aspect=16/9 -vf
pullup=8:8:8:8:-1:1,softskip,scale=720:480 -of mpeg -mpegopts
format=mpeg2:muxrate=36000  -fps 60000/1001 -ofps 30000/1001 -o
/Users/me/output.mpg /Users/me/source.mpg

framestep

mencoder -oac copy -ovc lavc -lavcopts vcodec=mpeg2video:aspect=16/9 -vf
yadif=0,framestep=2,softskip,scale=720:480 -of mpeg -mpegopts
format=mpeg2:muxrate=36000  -fps 60000/1001 -ofps 30000/1001 -o
/Users/me/output.mpg /Users/me/source.mpg

Could it be that the nature of the source video can be blamed for the
seemingly ineffectual filter commands? I'd be happy to supply a link for a
sample of my source if you'd care to help me investigate. Thanks again.
