So is it piping the files to ffmpeg?  Anyway, I tried the command
exactly as you suggested and it failed.  Unfortunately, I don't have
the error message handy, but I think it couldn't find ffmpeg.  I know
that doesn't help you much, I'll post the error message later.
 
I tried -o img%d.png and it complained something like: error creating output
file for each image.
 
However, this might all me moot.  I saw in an earlier post that you suggested
I update first and I haven't.  My mencoder is at least a year old.  So, I'm assuming
my problems are because of an older version of mencoder.
