[MEncoder-users] playing encrypted DVD?

[SZABO Zsolt]

I have recently purchased a DVD which I can't play:

$ mplayer dvd://1
MPlayer 1.0pre7try2-3.3.5 (C) 2000-2005 MPlayer Team
CPU: Intel Pentium 4/Xeon/Celeron Foster (Family: 8, Stepping: 9)
Detected cache-line size is 64 bytes
CPUflags:  MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1
Compiled for x86 CPU with extensions: MMX MMX2 SSE SSE2

Playing dvd://1.
Reading disc structure, please wait...
There are 1 titles on this DVD.
There are 24 chapters in this DVD title.
There are 1 angles in this DVD title.
DVD successfully opened.

[..here it hangs..and after Ctrl-C:]
MPlayer interrupted by signal 2 in module: demux_open

After trying the totem movie player it plays the intro then it gives up 
too, saying: "The source seems encrypted and can't be read
Are you trying to play an encrypted DVD without libdvdcss?"

The mplayer was compiled with libmpdvdkit2. [./configure said:
Checking for DVD support (libdvdread) ... disabled by libmpdvdkit2
]

What should I do? Have I left out something?
