[mythtv-users] uPNP sources wrong IP address

[Blammo]

Trying to make uPNP work with a Vista desktop.. The MBE shows up as
having videos to share, has all the right filenames, media descipt
data, etc, but when I actually go to watch one, windows media player
says it can't open the URL.

Upon examining the URL its' being fed, it's the IP address of the
Tuners box (SBE) not the MBE. I've looked at all the uPNP config I can
find, and can't see what might be wrong.

Any ideas?
