Playing DVD's

[Mark Knights]

Hi all,

I thought the Totem Movie player would be able to show DVD's but when I 
put a DVD in my DVD ROM it is not giving me the option to play the disc 
and when I hit the play disc command under the movie menue it tells me that;

Totem could not play 'dvd://'.
No URI handler implemented for "dvd://"

Do I need to add a plugin or there are more sinister forces at work?

Cheers

Mark
