IF you have FCP6/Compressor 3 (Studio 2)
I would shot the camera on 720P @ 24PN (which will actually be 23.98) Then you can transcode your footage in compressor. ON the Frame Control Tab you set Frame Control ON and then at the bottom change the Set Duration to 23.98 to 25FPS in the drop down menu. You also start with a DVCProHD 720P PAL setting. This will give you the best conversion without sending money.
