I'm editing with FCP on a MBP, using the DVI to VGA I have the laptop hooked up to my LCD TV. Normal use works fine, mirror screen and even as a second works. I can playback QT on the monitor. However when using with FCP I can't playback. Actually having FCP set to use the external causes no video playback on my TV and even on my laptop screen (Audio does playback) when I stop playback I get a freeze frame of the video on my external. I can scrub through my timelines and that will display the single frames, but can't get realtime playback. I've gone through the setting I have it set to "All Frames" not "Single Frame" in the playback settings. I got no clue.
