The “Unable to connect to background process” and “Unable to submit to queue” messages are common errors that unfortunately have many causes. Before you do anything else, check that your version of Compressor is compatible with your operating system. Only the versions included with FCP 5.1.x and 6.0.x are compatible with OS X 10.5. If you have an incompatible earlier version, you will need to either upgrade Final Cut Studio or downgrade your operating system.
