You have two instances of -lavcopts, which is surely ruining
everything....

You are using a filter (pp=de) AFTER the telecine step, which must be
destroying the picture, as it isn't meant to operate on interlaced
frames...

You aren't using softskip (preferably very near the end of the filter
chain) which may potentially cause problems.

 -mc 0 is probably causing the error message in question.  I would
guess that's, because your input isn't 30fps.

You haven't set ANY bitrate, so the default bitrate for transcode may
just be lower...  You also aren't using any quality-improving options in
mencoder, so you should expect inordinately large files.  Read the
HTML docs...

Yes, -vf telecine does hard telecining, which really increase the
framerate by 20%.  For soft telecining, you want "-mpegopts
telecine" .
