Attempting to view footage on external monitor while editing in Final Cut Express HD. Analog S-VHS (Y/C) Signal captured into Final Cut and re- directed out to monitor through Canopus ADVC 110 Converter. Normally I can scrub sequence and view edits realtime on monitor. Suddenly, can't do it anymore! Tried "Refresh Video Devices" under "view" options ... no luck. Seems to be some combination of selecting "Canvas" or "Viewer" and/or "Apple Firewire NTSC" Output. Any suggestions?
