Media Center Extender for XBox

[Aaron]

Antispyware on Media Center PC causes MCExtender for XBox
to continuously disconnect from the PC.

Aaron - this is an issue which is called out in the Known Issues section of
the download page.

Here's a KB article describing the problem:

http://support.microsoft.com/kb/892374 Windows Media Center Extender cannot
establish a remote connection after you install Windows AntiSpyware (Beta)
on a computer that is running Windows Media Center Edition 2005

I believe the workaround is to uninstall Microsoft Antispyware.
