That is correct. Coding the pulldown into the disc is wasteful. Another
reason to leave the formatting to the player. One would assume that
the DVD forum does not want to fall back behind the DVD standard in this
regard. What I hope is they go beyond DVD and do not assume interlaced displays
and prefilter the pictures on the discs. I also wish they were no color
subsampling and it were 10 bit, but that won't happen.
