Why are you reading the manual, sorry that is a bad joke, since nobody seems to read the manual before they post simple questions. (which yours is not)
I did a quick test just to make sure that things didn’t change with the massive upgrade to DVDSP 4.2, okay another bad joke, but the inspector still says the footage is 29.97. That has always been explained is this is the way a DVDs TC works and then when a play is setup correctly, Progressive, and hooked to a Digital TV the video streams that are flagged as 24P will in fact be 24P.
I have to admit this seems backwards. But if you step throw the video in DVDSP timeline you will see that there are duplicate frames for the pull down but the same file viewed in QT will not have those frames.
To test the final DVD you can step through the video and you should not see any of the duplicated frames.
