Is it choppy when viewing the video stream live? If it's only choppy when viewing it after it's been recorded, then changing the camera's settings will probably not do any good. The problem would likely be either in the recording software or a resource issue with the computer doing the recording and/or computer playing back the file.
The next step would be to determine exactly where in the recorded video clips the choppiness is occurred. For example, if you play the clip 5 times, do the "chops" occur at the exact same spots in the video or do they occur at different spots each time you play the video. If the skips/chops occur at the exact same spots each time you play the clip, then the clip was likely recorded with the errors due to the settings of the recorder and/or an error or resource issue on the computer while recording.....If the skips/chops happen at different spots in the video clip each time you play it, that will prove that the video recorded fine and that the problem is either in the playback software or a resource issue with the computer playing it back. Can also test this by playing the clips on different computers
