Standard DVD's can be encoded using either frame rate. I should have been more specific. From what I understand, most current major studio DVDs are 23.976 and the 3:2 pulldown happens at the DVD player for standard NTSC television. However, on an HDTV with a progressive scan display, no conversion needs to be made and the DVD plays actual 24p (well, 23.976 really).

Also, you either misspoke or you are mistaken about the pulldown from 24p to 29.97 being "-0.1%". A pulldown of .1% is a change in speed used to go from 24 to 23.976. In film being telecined to video, a .1% pulldown is followed by a 3:2 pulldown. Going from 23.976 to NTSC requires a 3:2 pulldown which is not a speed change, but rather an addition of repeated video fields to go from 24 frames to 60 interlaced video fields.

Sorry to be so nit-picky but, after all, this is "THE definitive explanation of 29.97 and 23.98" frame rates, right?

Not that Wikipedia is the most reliable source in the world, but there is a pretty good article on 24p that supports my understanding of how this stuff works.

24p - Wikipedia, the free encyclopedia
