Darren,
I saved the job and exited Compressor. (I would have trashed the whole set up but it would have been rather time consuming to recreate it again.)
I opened up Compressor again – checked my AppleQmaster settings again – I literally checked/ unchecked a radio button. (In this case it was the first one “SHARE THIS COMPUTER”. Clicked “OK” and then re-encoded the job and my virtual cluster was back where it should be.
NOW; saying that, if I’ve been running my MBP at the same time with Compressor running, on the same network, and have clicked on “SUBMIT” and placed a check mark in the “CLUSTER: THIS COMPUTER, THIS COMPUTER PLUS”, I’m finding that I have to reset my virtual cluster on my MacPro (even after my MBP is turned off) when next I want to use it in the virtual Cluster mode.
This works for me, Darren and while it may not be terribly elegant, it’s something that I’ve resigned myself to when this happens.
I’ll try and put something together and post it here on the actual steps I take; should make it clearer.
Good luck,
Lawrence
