    Is it true that the film originated material recorded on D-VHS tapes can not be shown in its true 24 fps native format? The ATSC specifications only seem to allow 24 fps for progressive 1080 (not in 1080i used in D-Theater). If this is true will movies on D-VHS still have motion artefacts from 3:2 pulldown?

    The "native format" of most HD broadcasts, and also most D-VHS tapes is 1080I, not 24fps. You would need an external processor such as the Faroudja DVP5000 to do 2:3 reconstruction on these sources. That said, I have never seen anything like a "motion artifact" on any off-air HD program, or HBO-HD or Showtime-HD.

    1080i and 24fps are totally different things!

    1080 is the resolution and scan type

    24 fps are the FRAMES PER SECOND

    they have nothing to do with one another, and theoretically yes, DVHS should be 24fps.

    I agree it SHOULD be, being a relatively new format and all, but I'm not so sure it really is, since ATSC dosn't allow it. We all know that tampering with the frame rates of the source will result in inferior picture quality. Perhaps most Americans don't bother about repeated frames in the 3:2 pulldown process because they are just so used to it (been watching it since childhood).
