  * Changed libdvdcss API to force binary incompatibility. Yeah, this is
    evil, but if we don't do it now we'll have to do it when more people

     o --with-dvdcss=no: build libdvdcss, dynamically link vlc against it.

     o --with-dvdcss=/foo: don't build libdvdcss, use libdvdcss from /foo/*.
    (this looks a bit strange to me, I'll find better flag settings)
