If you make a change, then render, the DV info is
rendered into a new file; if you make a change in
that part again, the rendered files "evaporate" (as
indicated on the timeline) and will not play with
any changes shown until rerendered (unless you have
an RT card - but for DV output, most of these still
require rendering...) and a new rendering is made
"from scratch"; if you export the rendered file as
an AVI and then reimport it and make changes, you
will cause a second generation of rendering. The
quality of the rendered image is dependent on the
quality of the DV codec used, and can show noticeable
changes with as little as one generation with a poor
codec, or very little change even with ten generations
(for an example of 10-generations of forced rendering
with a good codec [Canopus], see:
www.David-Ruether-Photography.com/original_vs_10th-gen.htm).
