HDV can be confusing, especially with new codecs being introduced with the HVX200 - I'm hearing different things left and right. But one of the main reasons HDV is troublesome to edit natively and cannot be scrubbed through as quickly is that the codec basically records a frame here and there, then makes an intraframe between each of those keyframes, by basically interpolating the in betweens. So whenever you make a cut, you're cutting off keyframes and the computer has re-interpret the keyframe/intraframe sequence of the clip - if you cut off a keyframe, the computer has to assign a new one, then make new intraframes. Which is what confuses the timecode, or so I've heard, so you can't edit in SD then re-import in HDV. With new codecs on the new HD cameras, you may be able to do that, though they'll take up more memory. Btw, how's everyone like the HDV codec - I've heard people hate it, because the intraframing can really distort quick movement and out of focus shots pretty much screw up codecs intraframing. I haven't seen a ton of footage, but from what I hear, HDV is not sounding tempting.
