2 brief points I thought I could add...
First, the 13 GB per hour HDV content is already compressed in MPEG2 and
cannot be further compressed without comprising its' quality, whereas the 13
GB per hour DV content is only lightly compressed and can undergo conversion
to MPEG2 (or other formats) with the resulting file occupying around 3 to 4
GB per hour.
Second, the new, lower quality Sony HD camcorders are not, strictly
speaking, HDV format. The HDV format camcorders are 25 Mbit/sec devices,
whereas the latest "AVCHD" format consumer camcorders are 15 Mbit/sec.
