[FireWire]

I've been having a problem for a while with my system.. On some sites, notably Dailymotion and Viddler, I can't watch video at all. On dailymotion, it will only display a black rectangle, and with viddler, the play button will register a click but nothing will start. I tried with many browsers (Safari, Webkit, chrome, Firefox, etc) but nothing works. My flash plugin is up to date (and the problem was present with earlier versions). I uninstalled flash completely before reinstalling but it doesn't work. Any idea?

I'm running 10.6.8.

Obviously it's a problem with Flash, but I seem to be the only one having this problem so it must be my installation. I find it strange that it happens with all browsers and only with specific sites. Youtube and most other Flash things work fine..
