I tweak my options case by case, but usually they are pretty much like
this particular example, where the source was a non-anamorphic NTSC DVD:

mencoder \
    -ofps 23.97602397602398 \
    -noodml -sws 5 \
    -vf dsize=108/79,crop=708:382:4:48,hqdn3d,scale=592:352 \
    -ovc lavc \

I use mplayer and try to stay away from windows, but the problem is
the people I encode videos for. I don't always have control over their
codec selection. Where I do have control, I have installed mplayer and
told them to use that instead of windows media player.
