Is the camera a 750i the " i " is the important bit. If it has this means it has video pass through capabilities, which means you can plug the video player in to the RCA sockets on the camera, switch to playback mode and check that AV-IN - DV is enabled in the playback menu of the camera. Connect the camera via firewire to the PC and press play on the VCR.

The camera will take the incoming signal from the VCR and convert it on the fly to DV and then send it out to the PC as DV-AVI ready for editing.
