This is a part of a major legacy issue… I’m having the same problem – when I try switching to Quickcluster with Services I get a “qmasterd not running” error message.
I had this issue in Compressor 2 and the workaround was to open Terminal and type “sudo /Library/StartupItems/Qmaster/Qmaster” then my password, then “exit.” Magically, “this computer” would appear in the cluster config dropdown the next time I opened compressor and I could use everything normally until the next restart.
I’m about to call Apple and see if my 90 day tech support is of any use.
