The way I look at it is this: 720p and 1080i both look absolutely
gorgeous for any type of content. Interlacing, however, is an
artifact of the 30's and a huge pain in the ass. It was a mistake to
include any type of interlacing apart from a single NTSC mode in the
ATSC spec. They also could have used this as an opportunity to
eliminate the weird frame rates (24000/1001, 60000/1001).
However, we are stuck with all of this madness.
