you have an older version of flashflayer or your Java is turned off?

Previous information about whether "jusched.exe" is running I got from him and may not have been correct. I am on the problem PC now and do not see jusched.exe running in task manager with either IE or FF.

I got videos to play in IE. The problem was the add-on "Shockwave Flash Object" was dissabled.
But I still get the same error in FF.

Ok I got videos playing in FF. I'm not sure but I believe the culprit was that he had 'Accept Cookies from sites' turned off in 'Tools > Privacy.

Is NoScript installed?

I'm not clear here on what is and isn't running.

I know those scripts can be enabled and still by default be turned off with NoScript running.

NoScript is not installed.
Jusched.exe is not running.

I was able to view You Tube videos with IE after enabling the add-on in 'Toolbars and Extensions' named "Shockwave Flash Object".

I was able to view You Tube Videos with FF after enabling 'Accept Cookies from sites' in the 'Options' settings under the 'Privacy' tab.

As far as I know these are the only changes I made to get the videos to show. They are playing fine now with both browsers.

Sorry for the confusion in this thread. I posted information that he gave me that I now believe was inaccurate. I know not to depend on him for facts again! 

Thanks to everyone who helped.
