  Still seeing this, QuickTime reports between 1% and 2% packet loss, 
still see loss with rtpqual.

  I have a machine in my office on the beacon now, 
netmenderx.cc.ndsu.nodak.edu.

  Looking at the beacon I see that ssb-vaiodesk.nts.umn.edu 
consistently is showing a loss of 5 from hendrix.multicasttech.com.  My 
i2 feed does come from the Northern Lights GigaPOP at the University of 
Minnesota so perhaps that is related.  The University of Minnesota 
folks are busy with a campus network upgrade but they can look into 
this in a couple of weeks.
