I'll just repost a message (see below) by Andreas Schultz posted here
on 16 Dec 2001. (see the whole thread for more details)

maybe it's the reason for the black screen.
If it is, just try to wait 20 - 30 minutes.

It is definetly libdvdcss related. My guess is that is has something to
do with getting keys from RPC2 DVD drives and/or DVD's with new/unknown
keys. Switching to libdvdcss-0.0.3-ogle might be the best idea.
