Next time, use the DVCPRO HD 720p24 Easy Setup...that tells FCp to look for the 24p flags on the footage and remove the pulldown. If it still didn't do it, then the footage might not have been flagged properly in the camera. It does have two 24p settings, one for the 24p look, but still running at 60fps, and one for 24fps with pulldown. I have that issue on a series I am working on. We are mainly shooting 720p24 at 23.98, but one DP didn't shoot that way, they shot 24p, but the footage is 59.94, and just has the "film look."
Try running the DVCPRO HD Frame Rate Converter from the TOOLS menu. Make sure REMOVE PULLDOWN is checked.
