I’ve had this problem for some time. We have two nearly identical 2GHz Dual G5 machines with Extreme cards. On one machine we can feed audio into the G5’s audio in, select that as the source for the V/O tool and record fine. On the other slightly newer (but same model) machine this does not work and the only way to record is to turn off the external monitor. This means you can’t do ADR or any other process that requires you to see the images on the external monitor. Blackmagic say they can’t reproduce the problem so it seems I am stuck with it.
Like you I can’t believe that Apple thinks that this is the way a voiceover tool should work.
Where I have had to have images on the external monitor I have used Soundtrack Pro for recording, but this is another program that we don’t really know.
