That makes sense since I first noticed the problem after removing the 
Qt3 code from libmythupnp, during which I made the SSDP code not run in 
its own thread, so the PortChecker calls now are running in, and 
blocking, the UI thread.

Regardless, removing the 500 ms sleep from PortChecker does fix the 
animation delay, but my first set of changes to PortChecker caused some 
other problems and was reverted.  I am waiting for some testing of a new 
set of changes from those who could reproduce the problem the reverted 
changes caused. https://github.com/MythTV/mythtv/pull/1249
