Media Center Extensibility Host

I have been getting reports of an "APPCRASH" when I launch Media Center.

The "Media Center Extensibility Host" fails to load probably due to my

firewall, but Media Center itself loads and seems to run fine. My

question is, should I care? What does this host do? If I should care,

how do I allow this in my firewall config?

Windows Vista Home Premium...Here's the details
