Well, of course you can convert HDV to a lesser format such as standard def
DVD and thus make it smaller. Similarly, you can also take a DVD compatible
MPEG2 file made from DV, convert it to play on a cell phone, iPod, or Sony
Play Station, and make it one quarter or one tenth the size.

The point of my original reply was that the apparently identical capture
rates of 25 MBit/sec between HDV and SD video is a deceptive comparison
unless one takes into consideration the fact that one is already in a highly
compressed format (MPEG2) whereas the other (DV) is not. The fact that
further compression and down-sampling could be applied to either really
confuses the point IMHO.
