Hi(Bonjour)!
Look in camcorder's menu to find an VIDEO OUT setting. Think about connecting audio device as S-VIDEO doesn't carry audio signal.
Can you monitor Mac on camcorder LCD? If not, see FCE user manual at page 171:
+"Troubleshooting External Video Monitoring Problems+
+If you experience problems while viewing your sequence, there are a few things you can try.+
+To quickly choose a different video interface for external monitoring,do the following:+
+-Choose View > Video Out, then choose an output option.+
+If you cannot see external video on your monitor, try the following:+
+- Choose View > Video Out > Refresh Video Devices to update the list of connected devices.+
+Note: This is especially useful if you just connected an audio or video device without quitting Final Cut Express.+
+- If you are using FireWire and DV, check the FireWire connection between your+
+computer and VTR (or other DV FireWire device) and the cables between the DV device and the external monitor.+
+- Make sure output connectors are always connected to inputs, and vice versa.+
+- If your monitor has multiple inputs, make sure the proper input is selected on the front panel of the monitor or in the monitor’s onscreen menu.+
+- If you are using a DV FireWire camcorder to convert DV to analog video, make sure the camcorder is in VCR (or VTR) mode and that it is turned on."+
