Perhaps I am/was mis-interpreting these results.  I had assumed that for
NTSC, 60 "frames"/s were needed for decoding but perhaps a frame in this
context is indeed two fields as it is much elsewhere.  In this case of
course, only 30 frames/s is required for decoding.  If so, then all I
can say is "sweet".  :-)

So this one is out for NTSC.  But as was mentioned before, why would I
use IVTC (which should be enough to de-interlace back into the original
"progressive" content that something started out as) with another
de-interlacer, be it MIXER TEMPORAL, or (per below) MIXER
TEMPORAL_SPATIAL?

Abd this one is out too.

> MIXER TEMPORAL_SPATIAL + IVTC (1920x1080): 15 fields/s

Ditto above re: IVTC.

> MIXER TEMPORAL_SPATIAL + SKIP_CHROMA (1920x1080): 23 fields/s

Also out.

But this one is usable.

It would be nice/interesting to know how the above de-interlacer names
correspond to Myth's nomenclature.

Cheers,
