Yes.

I've seen lame do that when you've set a ridiculous low audio bitrate,
but not otherwise.

When mencoder reports a duplicate, it's because it is doing just that,
and omitting them from the output.  -vf harddup will STOP it.

It has to skip a frame to match your selected -ofps value, or to
maintain A/V sync.

It's already doing it.  -noskip and/or -mc 0 will STOP it.
