Media Center Extender forces Quiet mode (even when option is not selected)

Hi all, new user here, just loaded NIS 2010 on a Windows 7 machine.  I have a linksys media center extender that I leave on 24/7.  I have discovered that whenever I connect the extender, NIS goes into silent mode.  I get the following in the history: A program entered full screen mode. SIlent mode is on.  In the settings, I have turned off all silent mode settings, the full screen detection, media center TV recording and IMAPI disc burn.  I have rebooted multiple times.  BUT, every time I connect the extender, I get silent mode.  This seems like a bug to me.  Can anyone help on this?  

 

Since I leave the extender on 24/7, NIS will be in silent mode 24/7.  As I understand from the help files, that means LiveUpdate, pulse updates, and other scans will not occur.  Is this correct?  That seems like a big problem.

 

Any Advice?

Thanks
