[wplug] is it possible to crop MPEG2 video without re-encoding?

I have an MPEG2 file captured from a TV show.  I'd like to crop the
black bands off the top and bottom, but otherwise leave it alone,
since the encoding is good quality (produced by the hardware on the
tuner card).

The only ways I've found so far involve mencoder with the crop filter,
and require me to re-encode the video -- which means choosing from a
maze of twisty little parameters, none of which seem to produce as high
quality as the original input, and some of which even result in a
larger output file.

I'd appreciate any help.  Thanks.
