   I have no idea what it is you are referring to by the terms =
"encryptor video device driver" and "unencryptor for the
video input on = the
display device".  Are you referring to something relating to HDMI or = HDCP?  I
believe that's all hardwired in the hardware.

  Ok, so there is a driver for the DVD drive, then there is a filesys =
