My Compressor issues solved

UPDATE 11/9/2008: We've now released a tool to automate this fix, called Compressor Repair.

I recently experienced the dreaded "Unable to submit to queue. Please restart your computer or verify your Compressor installation is correct" error message when submitting batches with Compressor. I noticed that it listed "No Value" under Cluster instead of "This Machine".

Going to Qmaster Preferences and clicking Start Sharing gave me a message saying that "qmasterd" was not running. This was the cause of the problem.

The first thing I did was look on Apple's support boards where I found many posts on the subject. Unfortunately most users found that they managed to solve their issues by removing and reinstalling Compressor or the entire Final Cut Studio. This is something I did not want to do.

I used the terminal command sudo qmasterprefs -reset (this seems to be equivalent to trashing prefs as far as I can gather) and then sudo qmasterprefs -restart to relaunch qmasterd. I then relaunched Compressor and everything worked as it should.

Except when I restarted my machine, at which point I was back to the same error messages again. I knew that a fix must be possible without a reinstall, and it was probably something simple. So I did some digging around and I discovered that the folder /Library/StartupItems/Qmaster had the wrong permissions. It was set to No Access for some bizarre reason, preventing OS X from seeing any files inside it. Note that this was not picked up by Disk Utility when doing a permission repair. So I set the owner back to system and clicked Apply to enclosed items to be 100% sure that the permissions would be correct for all files.

I restarted my machine and everything worked. Two restarts later and it still works.

I can't say it will work for everyone but try it if you are experiencing these symptoms.
