Hi Colt This error with compressor is tied in to upgrading compressor and how it interacts with Qmaster. I also battled with this problem a while a go, and finally got it sorted out after many chats with Apple. The solution that I detail below is ONLY for OSX 10.3.x If you try to use this under 10.4.x you will kill your Mac and keep getting a kernel panic on start up, you will have to go into the disk from another Mac and correct the files placement if you do this on 10.4.x. This is not a issue as I have not had this problem since going to 10.4 and using compressor 2 so try this and it will fix your problem, worked every time for me, after system rebuilds etc.. 1. Quit all open applications 2. In the Finder Menu Bar > Go > Go to Folder... 3. Type "/etc" 4. locate the file named "hostconfig" 6. Command-drag the file to the desktop 7. You will be asked to authenticate as the admin user - do so 8. The file is now on your desktop 9. Keep the /etc Finder window open 9. Rename the hostconfig file on your desktop to hostconfig.old 10. Command-drag the file back to the /etc folder 11. You will be asked to authenticate as the admin user - do so 12. Restart the computer and zap the p-ram twice on restart [command +opt+P+R] if you have to do this at any time in the future due to a rebuild then include the following 4a Locate the file named "hostconfig.old" (this was the file that was created the first time I did this) 4b Drag the "hostconfig.old" file to the trash and reboot 4c On reboot locate the file named "hostconfig" ...
