I was unable to attend the last Microsoft Expert Chat for Media Center but it looks as though these are going to be monthly events again.  I headed back to take a look on a whim and found that the next session is scheduled for November 20th at 4pm pacific time.

These chats are listed under Windows XP Expert Zone chats but from reading the transcript of the last one, it looks as though the experts hosting the chats are helping with Windows Vista issues.

If you’re having issues with your Media Center that no one else seems to have been able to help with, I encourage you to attend the next chat session!  If not, there’s always good info to be had during the sessions.
