dd of a DVD fails unless I first view it with VLC
When I buy a DVD, I immediately rip it to an ISO, then transcode the movie or episodes because that's faster than having HandBrake read directly from DVD.
The problem is that dd quickly barfs with an IO error when reading protected DVDs except when I first view (even for just a few seconds) the DVD with vlc. Then dd works perfectly. Presumably this has something to do with reading the CSS keys.
So, does anyone know of a CLI tool that will read the CSS keys and place the results in ~/dvdcss ?
