Stewart,
This shows you how, only note that the last step of renaming clips is more streamlined and you do it from the browser.

Not sure if your drive is fast enough, but give it a go.
Yes, capture the whole tape, FCP will start a new clip for each time the camera was turned on. Then you simply open each clip in the viewer from the browser, and if you want to keep the clip, type in a new name in the browser. I open the capture scratch folder so I can toss clips I don’t want. then delete the clip reference in the browser. When you are done re-naming, select all the clips in the browser and right click rename, file to match clip, and you will see that all your WT clips are changed.
Have a wonderful day.
