The DV codec is fast for compression as well as playback, it's very
optimized in QuickTime, and uses MUCH LESS drive space than "None"
compression (less than 4 MB/sec for DV vs. 27 MB/sec "None")

If you do a DVD, Apple's MPEG-2 encoding is highly optimized for source
using the DV codec, if you go to VHS, just drop it in iMovie or FCP and hit
play (no re-rendering).  (note:  iMovie would use a "DV Stream" file, and
FCP uses the DV codec inside of a standard QuickTime file)

As long as you work at 720x480 (with DV aspect rectangular pixels) and 29.97
fps, you'll be set.

ROTFLOL!!!  HAHA!!!  (actually... same here :-\)
