As a rule of thumb, any CoDec associated with the Apple Pro applications is generally not available on Windows. This also includes their flavor of HDV. The only exception at this point is ProRes, for which they added a player component recently. So therefore this would have to be what you use for capture/ export from FCP. Apart from that you can of course always buy a capture card from Blackmagic or AJA with the benefit of the CoDecs being available cross-platform... Or you use a commercial software-only CoDec like Cineform.
