Canon XH A1 and Project settings for 24F
 

Before capturing in Edius 5 from Grass Valley I need to set up project settings AND capture settings. In project settings I set frame size to 1440 x 1080 and 24p. But in capture settings I have different options. The three I see are: (all at 1440 x 1080) 25p, 23.98p over 59.94i AND 23.98pA over 59.94i. Can someone tell me what are the reasons are to use these when I capture at 24F on this camera?

Thanks in advance!

How about 23.976
