My questionis, if you are going to broadcast (29.97), why would you shoot 24PA and edit 23.98 fps? What could you possibly gain?
Keep it simple. Shoot 24P, capture and edit 29.97, and output 29.97. Do not muddy the waters by going 23.98 then trying to go back. It makes no sense, and opens the doors to huge workflow problems. The less complex your workflow, the better.
