RealPlayer Autoupdate Error with Mplayer Plugin?

[Benjamin Sher <delphi123@zebra.net>]

Dear friends:

I am very pleased with my Mplayer plugin in Mozilla. However, when I try to 
run RealPlayer embedded files I get

http://www.johnkerry.com/

(To to right column, middle: Recent TV Ads, A Good American, Real, DSL)

I get a strange error message:

"You do not have the necessary user permissions to enable Autoupdate. "

What in the world is RealPlayer talking about?

On the other hand, if I select the same clip using Windows Media Player, it 
works flawlessly.

Would really appreciate help on this.

Thank you so much.

Benjamin
