Totem won't play.

[Keith Powell]

For the first time, I am trying to play a commercial DVD. It's a 
publicity "holidays" DVD so I suppose that it shouldn't be encrypted.

I'm trying it with Totem, but it won't play. Tells me that I haven't got 
the necessary plug-ins installed.

What plug-ins are these, please? I'm using Ubuntu "edgy".

With KDE and Kaffeine, the DVD plays "out of the box". But I would like 
to play it in Gnome.

Many thanks
