Mike, There's no clear answer yet, but we've seen the problem occasionally on multiple systems, ruling out a distribution related solution. Can the problem be consistently reproduced? One thing I've noticed is that sometimes the problem has just gone away if I come back to it another day. Another thing to try is to re-enter the venue. This updates the stream information in the VenueClient from the venue i.e. the service in question may then be using "better" stream information. chris > -----Original Message----- > From: Mike Weaver [mailto:[email protected]] > Sent: Thursday, February 01, 2007 13:29 > To: 'AG-TECH list' > Subject: RE: [AG-TECH] Video Producer Service fails to start > > Hi all, > > I finally had time to start looking at this again.
