Extremely weird field orders

The big disadvantage of this method is that most 60 hz content is effectively reduced to 30 hz anyway, but with more jerkiness and frame-blending than if you had just used the first method.
It doesn't matter anyway, as this is exactly what VCD requires.

For VCD you can simply discart one field as it have exatly have the vertical resolution of an SD signal, and no one is goint to notice unles is some special case (I only remind one in and old show where for about a second te top and botton field where of different footage during an explosion, basically a crude way to supperpose the images, it was actually an explosion).

Yes, it definitely makes a mess of interlaced video.

Yeah, Gargoyles did the same thing for the title card.
