Recently, my Safari has been showing me the rainbow beachball on any site that has embedded video. For example, going to the New York Times site or MLB.com just completely disables the browser. The same problem occurs with Firefox and Camino. The only recent change that occurred on my computer was that Spotlight decided to re-index for no reason. I am running 10.6.1. I also upgraded Flip4Mac WMV to the most recent version, and the problem persisted.
