I'm working on setting up a h.264 pro recorder on an iMac for our church. Setting up the video and audio was a breeze, but for some reason whenever I am on the "Log and Capture" screen in Media Express, the iMac seems to send a delayed audio feed of the recording through the headphone jack. This is a problem as the computer is a presentation computer which is used to play videos and music in addition to recording the service. I cannot simply mute the computer at the board to solve the problem. I need to be able to play audio from another program while recording in Media express without audio monitoring the signal.

Any fixes?
