I think Handbrake does something like that, it "plays" the disk, obeying the 
disk's instructions on what sectors to go to, then transcodes as it plays. I 
think it uses VLC to play the disk.

Certainly an "access list" such as you describe should work.

But this thread is getting dangerous, at least in the Land of the Free. The 
DMCA precludes even discussion of methods to circumvent any protection scheme, 
no matter how lame it might be.
