He Said Cineform, not HDV, Cineform is an intermediate codec used to take a load off the CPU by doing all the "Reading between the lines" for the cpu while the footage is being captured rather than the CPU having to decode all the macroblocks individually while it's being edited, it has been reported that Cineform has actually ran on a 1.3Ghz machine at some points.
That said, as for fast motion being a problem for HDV, this problem is less notable on lower resolutions and framerates, however obviously the sampling is not as high then also as video processors become better then the problem starts to become less notable... What you really have to watch out for are Linear sensors...
Quite a few of the "Cheaper" Sony HDV cams scan the sensors from top to bottom in order, this isn't too bad on 50 or 60fps however if you film at or deinterlace to 24/25/30fps it looks horrible and there is an obvious lag on fast whip pans or zooms between the top and bottom of the screen.
It's not about what camera you use or how much it cost.
It's about what you shoot,
how you shot it,
and how you edit it :P
