I believe the above is not quite correct. So far as I know, its only   
arccos that makes dd fail. css is an entirely software-based   
encryption, on top of the data on the disc. dd operates at the block   
device level, css never comes into play. What arccos does is embed   
corrupt blocks of data on the physical media, which is what makes dd   
fail.

Not mentioned are dvdrip (different from lxdvdrip) or handbrake.

I'm quite partial to handbrake myself (though the linux version isn't   
nearly as slick as the Mac OS X version, can't comment on the Windows   
version, never tried it, I don't do Windows).

I know a few of the guys on the mythbuntu team, they're good guys and   
do good work. Would be nice if I could work on MythDora on company   
time and keep it in sync w/Fedora, but there's that whole legal   
thing, so Red Hat won't (officially) touch it w/a 10-ft pole... :\
