totem doesn't play dvd: no reason

[Gianluca Cecchi]

After recompiling from source rpm packages from gstreamer site:
gstreamer-plugins-ugly-0.10.1-0.gst.1.4
gstreamer-ffmpeg-0.10.0-0.gst.2.4
gstreamer-plugins-ugly-devel-0.10.1-0.gst.1.4

and recompiling livna packages:
a52dec-0.7.4-0.lvn.7.4.src.rpm
djbfft-0.76-0.lvn.4.4.src.rpm
lame-3.96.1-0.lvn.4.4.src.rpm
libdvdcss-1.2.9-0.lvn.1.4.src.rpm
libdvdnav-0.1.10-0.lvn.1.4.src.rpm
libdvdplay-1.0.1-0.lvn.3.4.src.rpm
libdvdread-0.9.4-0.lvn.1.4.src.rpm
libmad-0.15.1-0.lvn.1.b.4.src.rpm
mpeg2dec-0.4.0-0.lvn.4.b.4.src.rpm
amrnb-0.0.1-0.lvn.1.src.rpm

I'm able to play with latest fc5 devel totem (totem-1.3.1-1) various
video files, and also divx.
Trying to play dvds I get
"totem was not able to play this disc.  No reason"
If I want to stay with totem provided and be able to play dvds where
it is legal, what other requirements should I add?
Or have I to install necessarily totem-xine?
