DVDs are not burned in FPS, but rather burning speed 4x...8x...16x, etc. Frames per second is determined by the original image content. The only way to change the image fps is with a video editor or perhaps some DVD player may have this functionality in playback.

And neither PAL nor NTSC support 24fps directly. You have to fit 24-frame content into a 30-frame (60-field) "container" for NTSC, or 25fps for PAL. Usually for the latter it's just sped up.
Stuff like Adobe Premiere is useful for these things.

And to be really technical no information on a DVD is normally PAL or NTSC as the colour information is not held as a chroma sub carrier as in those two analogue TV systems. I believe only D3 digital tape held the signal as composite video.
As you put itm they are respectively 625/50 and 525/60 signals on DVD.

OK,I got the point.
Yes,there're some software that will accept 24p video stream,and natively author 24p DVD out of that. By placing "flags" in the authored DVD that will tell the player to add pulldown and output it as 60i. Some (presumably) higher-end player will even output pure 24p video - if the display device can support that. At least that's what Sony DVD Architect pro/studio do.
