Good you got it working, and yes, that is the URL used by mythfrontend
to retrieve all the available grabbers from the master backend.

I can't see how opening those ports would have helped for this problem 
though, unless you have changed the configuration from its default. 
Port 6545 is for mythlcdserver, 6546 for network control of 
mythfrontend, 6547 for mythfrontend's service API, and 6948 for 
notifications.
