I just installed smplayer like this: sudo apt-get install smplayer
Then I went to System Settings > Details (poorly named) > Default Applications
I changed both video and audio to be handled by default with smplayer (I actually suggest making it the default player in the upcoming release).
However, if I now go to an audio or video file, and double-click them, they still open in Rhythmbox and Totem (respectively).
Changing default applications doesn't work yet in 12.04 Beta 2.
