Agreed.  This is a good way to go when the data is already digital.  If
one was planning to replace all of the old film footage of the hollywood
studios, then the D2 approach might be better.  A basic system to
accomplish this should be easy to construct.

This is all true, but as far as I saw, the original footage was DV 
quality at best. I heard no mention of BetaSP, D1, or D2 footage in its 
source state.  Since that is the case, there is nothing at all lost by 
storing footage in DV format, and a lot of space gained. DV is in fact 
compressed at 5:1, using  discreet frame constant bit-rate compression. 
It makes it an excellent choice for future editing for video or web use.

There is also a product on the market, I believe the name is CatDV 
(shareware) which will catalog DV tapes, and allow indexing, keywording,

search and retrieval of footage. This makes it practical to use actual 
DV tape as the storage medium, and then use automated machine control 
for retrieval and digitization of content required for a specific 
project. The purpose here is that DV tape is a fraction of the cost of 
hard disk space as well as maintenance free. Because of the frame 
accurate machine control, DV can be considered a digital archiving
