have the same problem here !
if there are placemarks in a .kml that is referenced by a network link the 
ballons wont popup... the same goes for a tour... this is VERY for me since i 
try to play a tour and the placemarks have no info

HOWEVER when i load the same kml with javascript again... it shows the balloons 
when i play the tour again .,.. very weird..

Similar problem in Google Earth.

I cannot get the         <gx:balloonVisibility>1</gx:balloonVisibility>");  to 
work under any circumstance!!!

This works for me if the gx:balloonVisibility is for a placemark within the kml 
that is called by the networklink, but not if I put a placemark in the 
containing kml file
