DVCPRO HD FCP Framesize 960 x 720, HUH?

Can anyone explain this seeming oddity? In FCPHD I used Easy Setup "DVCPRO HD - 720p60" to capture my 60fps Varicam footage. When I look at the captured clip in the Finder it says the frame size is 1280 x 720, but when I look at the captured clip in FCP's browser the frame size is 960 x 720. When I look at the sequence settings or sequence preset for that Easy Setup, the frame size is 960 x 720 but video output is set at 1280 x 720. Why isn't everything set to 1280 x 720? How can the frame size be different in the Finder QT clip than in FCP's Browser QT clip? Did I do something wrong? Or is this the way it's supposed to be? I don't get it. Do you?
love,
