No url handler implemented for "..."

[Ted Gervais]

I have just installed fc6 and tried viewing a video on CNN website and I
get --
Totem could not play
'mms://wmscn.stream.aol.com.edgestreams.net/cnn/showbiz/2006/11/30/moos.devito.drunk.cnn.ws.wnv.'
"No Url Handler imnpletemented for "mms"

How do I get around this.  Does this mean I need to install a plugin?
Maybe mplayer?  Or does this message mean something else.
