Are you running totem-xine or totem-gstreamer?

For totem-xine, you might check in synaptic for the package 
libxine-extracodecs.
For totem-gstreamer look under "gstreamer" in synaptic for the codecs 
(match your version of gstreamer to the codecs).
Someone else may give you a cli string to use to search for these 
things, but synaptic does give a nice alphabetical list of available 
packages.  Also, you will need to have the universe and multiverse 
repositories enabled.

If you are not running 6.06, then go to the section for your version of 
ubuntu for the instructions.
Hope that gets you going.
