Regarding the DVDs:
AFAIK you cannot make changes to a full DVD, even if it is rewritable.
Rewritable on a CD (and I suppose the same for a CD) means you can
erase it all and start over. This is not the same as with a floppy or
similar media, but it is still a useful feature.
Of course, it is not a bad idea to put etch on rewritable media. You
can save some disks this way. Later, you can use jigdo's update feature
to use your existing DVDs to build new DVD images by downloading just
the changed packages. Then you can use the rewritable property of the
media to erase it and put the new images on it.
I hope this is clear enough.
If you can't explain it simply, you don't understand it well enough.
