All I know is that DV isn't so great for compositing.  Some people claim
that running DV through a S-Video link and back into a high quality
analog capture board will improve the compositing performance.  Other
people claim that running a blur filter on the U and V channels, or on
the whole image, helps.  In either case, it makes some sense.  And, this
certainly isn't something where better is nice for high end projects,
but not really nescesary.  If you need to do compositing, you will
probably save a lot of trouble by not using DV.  So, DigiBeta is
certainly better, but also far more expensive.  One option would be to
shoot for composites on rented digibeta gear and use your own DV for
everything else.  The other is to say you have more time than money and
just live with DV.  For the most part it certainly looks fine.

That's the only way I've seen film being done.  DDRs are still extremely
expensive.  Enough so to make one ponder throughing a SDI card a RAID
controller in a Mac to avoid the cost of the DDR.  I find it
disappointing the way these items maintain their price and then

Well, it was cheap.
