   Uh, talk about code maintainability! We use a more verbose but maybe
easier to understand implementation in plugins/dvd/dvd_css.c, it's in
CSSDescrambleSector(). I think ours might be a bit faster since we use
lookup tables for bit inversion. Anyway, I'm not sure anyone will fancy
adapting this code to vlc :-)
