Sigh.

You shoot anamorphic 16:9 DV. That records 720x576 to tape with
rectangular pixels.

You then crop off 1/4 of those pixels to get a 4:3 aspect ratio and
resize the frame back to 720x576.

You've now lost 1/4 of your resolution by throwing those pixels away
and rescaling.

What's so difficult to understand about this? Transcoding from 16:9 DV
to 4:3 DV will always lose a sizeable amount of resolution... you
cannot record 1024x576 to a DV tape with the DV codec.
