I'm glad we're not nuts!

Exactly :-)  Once libdvdcss authenticates the disc with the drive 
firmware (via xine, mplayer, vlc, totem, etc), then you can do 
anything you like until the disc is ejected.  Sometimes people have 
DVD-autorun enabled, so that the movie starts playing with their 
favorite player. but then they close the player and go dd the disc. 
If that happens, the CSS authentication issue gets lost in the 
background of your autorun app which utilized libdvdcss...

And now we're on the same page!!!  Btw, thanks for the MythTV talk 
last night.  My little brother is thinking about setting up a MythDora 
box at home for recording TV shows while he is at school (6th 
grade)...
