There is absolutely no way to measure that. If your dvd only contains document files or text, then it could possibly shrink it to 1/10th of it's original size. If your dvd contains files that are already zipped in some form, then the bzip2 compression could actually make the dvd larger
. You'll just have to try it out.
Also, if you want good compression, but at a faster speed, use gzip. The bzip2 takes about 3 times longer than gzip. (I usually use bzip2 though, because for me space tends to be more valuable.)
