I have two identical Mac Pros running OSX 10.6.8 and Final Cut Studio 3. On one, when I submit a job on compressor, it goes right ahead and starts the job. On the other, I submit the job and it thinks about it just long enough for me to move on to something in another room, and it decides to ask me for my password before it will continue the compressor job. There is such a delay that I often forget it and come back in the morning, and there is my unfinished job with Compressor still waiting for my password to get started. Curses!
Several editors have looked at my two systems and can't figure out why one asks for a password before starting the compressor job and one doesn't. I'm just tired of it playing me for the chump and hope someone can tell me how to keep it from asking for my password when I've already hit submit twice!
