Mencoder notes

1.) It is generally agreed that a single pass makes better videos at the expense of larger files.

2.) If 2 passes are used, motion becomes a blur (experience from home videos). Might be corrected for with a high motion detection factor (me_quality=6 in -xvidencopt), like here.

3.) To decode from raw DV, you'll need this codec (put it into MPlayer's codec folder).
