I am having issues trying to play my ime line through an external monitor. I am using a Sony DVMC DA1 convertor to a monitor but for some reason the video signal is not coming through through the FW cable. I have tested it multiple times through 3 cameras. I went to file>AV settings and clicked the video playback to apple FW ntsc and on the devices tab checked off mirror playback, but nothing. Am I missing a step here somewhere? I have had issues for years with various versions of FCP with sporadic external video playback and just trying to figure this out. I have tried it on 2 different machines as well. A 12 inch 1.5 PB running FCP 4.5 and a Quad G5 running FCP 5.4. Thanks.
