Playback isn't supported on this device

I get playback isn't supported on this device in most cases when attempting to view a youtube video.  When I attempt to install the newest Flash Player it will not install, with and without Kaspersky Internet Security turned on.  I am running the latest version of FireFox and my OS is XP Pro Service Pack 3.  None of the suggestions I have tried so far have worked.
