Actually, I disagree.  The most important factor for freezing motion is not
whether it's interlaced or not, but the *shutter speed* of the camera.  A
higher shutter speed (1/250 sec. or higher) will freeze the motion.  And if
this higher shutter speed was used with a progressive video signal (or even
"quasi-progressive") that should yield the clearest still frames and slow
motion possible.

2 cents.
