The only thing I can tell you is that I have exactly the same behaviour 
with the Windows version when I'm not logged in as an administrateur under 
WinXP.
What happens is that the DVD authentication necessary to the decryption 
process needs "ioctls" to talk to the DVD drive but you need enough 
privileges to use them.

So my advice is first to make sure you have write access to your DVD device 
(/dev/hd?), and also to make sure your linux kernel is recent enough and 
supports DVD ioctls (2.4.x kernels should be fine).

Cheers,
