As far as i know the firmware that was used for the clip sport is the same as the clip zip so you should be able to see the same options and navigation menu. The thing now for the recording is that the clip sport does not have this option as far as i know so sandisk didnt remove this menu option from it or they will build the feature to a future firmware release.
Unfortunately, you are incorrect. Each of the Clip, Clip+, Clip Zip, and Clip Sport has its own specific firmware and, as users of the various players know, some features are different in each player. This especially is the case with the Clip Sport, which has significant player limitations compared to the earlier models, due to hardware limitations. And the firmware for one player model CANNOT be used for another model.
Also, it is unlikely that any further capabilities will come for the Clip Sport in the future, due to its hardware limitations.
