That's correct, the PAL version of the DVX100A has only the PAL 25fps setting. You would not miss anything in that the 1 frame difference would not normally be seen by the naked eye.
(The NTSC version however is 24fps capable and the resultant 6fps difference is noticeable when compared with the NTSC 30fps norm).
Don't worry about it. 24fps can't be implemented in DV-PAL anyway (that I know of).
25p looks identical and is easier to handle when editing and outputing. Even a 24fps film blowup can be achieve by simply speeding up the footage by 4%. The speed difference is not noticable.
The PAL DVX also benefits from higher resolution (720x576). Only opt for NTSC if that is your output market, NOT just for 24fps. It isn't a big loss in PAL land.
For the resolution you capture with 20% more lines than NTSC but note that if you shoot in 16x9 you'll end up in square pixels in 1024x576 instead of 852x480 in NTSC. That is 44% more pixels. If you're interested in cropping to the 1:2.35 aspect ratio you come down to 1024x435.
There's no pull-down to deal with in PAL, and editing is easy.
The scene files 5 and 6 have two different cine like settings. I think in NTSC the difference is pulldown and advance pulldown.
Also if you're interested in keying which I've never tried neither on NTSC nor on PAL, note that the color sampling for NTSC is 4:1:1 and PAL is 4:2:0
