Comment 10 for bug 84245

Just dist-upgraded to gutsy, and Rhythmbox wont play anything if the visualization plugin is enabled, regardless of other video apps playing or not. If RB is loaded, Totem complains another video app has grabbed the video overlay, but plays anyway.

I'm sure you wont like me for this, but my video driver is fglrx (;_;)

It should be added, that this behavior is an improvement, previously attempting to use the visualization with fglrx caused X to crash instantly.
