DGPulldown question re: NTSC progressive scan DVD players

[Gav]

I understand that when a normal NTSC film based (23.976 fps) DVD is played back on a set-top progressive scan DVD player with inverse telecine and viewed on HDTV progressive scan TV that the fields are assembled correctly and you see the correct 23.976 fps frames. Now what happens when you view a DVD that was made from a PAL progressive source (25 fps) resized and passed through DGPulldown to convert it to 29.97 fps. How does the progressive scan DVD player with inverse telecine handle it? Do you end up seeing the original 25 fps frames or is that not possible on an NTSC HDTV progressive scan TV?

NTSC film = 24 p, though often won't get into trouble using 23.976 & 24 in editing software. At 24 p there are no fields -- just whole frames.

Commercial DVDs will normally retain 24 fps, using pulldown flags in mpg2 file to instruct players on which frames to repeat, how, to achieve NTSC 29.976 i when needed, as with std. crt TV. In the absense of these flags, the DVD player will normally do it's own pulldown as/if necessary. When you have 24 p, don't know why/how you'd do IVT.

Progressive DVD players are usually capable of progressive or interlaced output so they can be used with std crt TVs -- that way they can sell more progressive players at higher prices to folks who can't use them, but like the idea of progressive DVDs.

That said, I'd verify that you have 25 p -- to my knowledge it's fairly common to just set playback rate to 24 p. Adding pulldown flags will not do anything but add those flags -- probably as easy to leave them off, set rate to 24 p, and have the player add pulldown when/if necessary. RE: 25 p content w-w/out pulldown in an NTSC player, my guess is that it would probably depend on the player -- many read NTSC, PAL etc. RE: fps to HDTV, you're not actually dealing with the display, but with whatever device sends it video.
