24p means that it produces 24 FULL frames per second, not interlace frames.
Check the wikipedia link for details on how they compare, but needless to say, 24p is far better.,

The only way I can explain this is, I can't. You have to actually know what each looks like. However, that should be easy, considering you've probably seen at the very very least one newscast and one movie in your life. In NTSC television (which is what north america and japan is), the frame rate is 29.97 fps (we'll round it up to 30). So each frame takes up 1/30 of a second (there's a reason why it's not 30fps, but that's not important). However, each frame isn't recorded as a whole frame. Instead, every even line is recorded first, then the odd ones. So this actually becomes 60fps, with each frame containing half the information. And every half-frame (interlaced frame), takes up 1/60th of a second (1/30 divided by 2). Hopefully this makes sense so far. If you've ever seen video from a newscast, or your home videos, that's what it was in, 60i (get it, 60fps interlaced?). In movies, however, images are shot on film. If you've ever seen film (yes, it's the same kind), each time you expose it, it records the whole image, unlike video. If you've ever wondered why movies look different from video, it's because they're shot on film, and at a frame rate of 24fps. It's hard to notice, but if you put it side-by-side, it will become very clear. The HV20 mimics 24p, by producing images in the same way. Instead of normal video, where each frame is recorded in two passes, it records every frame in one pass. Therefore, the "P" stands for progressive, because no lines are skipped. And then it slows down the speed to 24fps, so when you watch it, it really looks like film. Obviously, this doesn't even come close to explaining all the details of why video and film look different, etc. but hopefully it helped.

24 frames only works if you intend on actually transfer to film.
American TV runs at 30 frames.
