No, but you do need to authenticate with the DVD-ROM drive. To do
this, at least under Linux, you have to invoke the proper ioctls, and
do a cryptographic authentication procedure with the drive. Code to
do this is covered under "circumvention device" in the DMCA according
to the 2600-MPAA case.
If you don't do this authentication, the drives I have worked with
will just spit out zeros instead of the real data.
