I understood that it DID decompress as well as decrypt since that was
necessary in order to output sound and video in a format that a conventional
animation player could deal with.

I read somewhere that a DeCSS-ified movie consumes between 10 and 20
GIGABYTES.  That's quite a bit more than a DVD disk can hold (I imagine).

The *whole* point here is that (currently) the ONLY way to get a copy
of a DVD is to *NOT* use DeCSS - but instead just copy the encrypted
files from the original disk onto a blank one.

If you DeCSSify the data on the disk, it gets A LOT bigger and won't
come even close to fitting back onto a writable DVD disk.

Exactly.
