totem on ubuntu 5.04 to play Finding Nemo mpeg2 DVD

[tom scott]

hello greetings ubuntu totem users:

I'd like to use the totem video player that comes with ubuntu 5.04 and
which I updated this very day (2005-03-23). According to the Synaptic
pkg mgr i have the totem and totem-gstreamer packages installed and they
are 1.0-0ubuntu2. The Help window, About Totem, indicates that it is
"Movie Player using GStreamer version 0.8.9" but I guess that's only
because they didn't have time to update the message in that window when
they updated to 1.0-0ubuntu2? Also, when I type "totem --version" this
is what it displays: Gnome totem 1.0

When I type "totem --help" I see that there are possible plugins and a
plugin path. I was wondering if someone can tell me how I can find which
plugins are installed? In particular how can I tell if I've got mpeg2?

The first few times I tried to use Totem I got some kind of message that
said I should run this script:
/usr/share/doc/libdvdread3/examples/install-css.sh
So I did. At least now I seem to get further but I still can't play the DVD.

I'm interested in mpeg2 because I'm trying to play some DVD movies while
I walk on a treadmill, sort of like having fun while staying healthy.
The movie I'm trying is Finding Nemo. Here's the messages that show up
in the terminal window when I try to get it to run the DVD when I select
Movie -> Play Disc:

I'm assuming that when it says mpegversion=(int)2 it means mpeg2. Is
that right?

anyways, can someone tell me if I can get this to work? I looked at the
ubuntuforums.org/archive but have not found the answer.
