I'm taking a look at the demo version of Glue Tools to work with DPX files inside FCP (and other QT-based programs). Seems to work very well -- except I can't get playback in FCP to play to the monitor and to my external monitor at the same time. I can get one or the other -- which is controlled by the 'mirror on desktop' switch in the A/V Devices window.
footage is 1080p23.976. All the 23.976 Blackmagic settings work -- play video to the external monitor or on screen, but not both.
Tried every variation I can think of. Quit. Restarted. Refreshed A/V Devices, etc.
Any suggestions to get video play on both external and on screen?
