I don't keep the disc image as raw footage because it would suffer  
being transcoded twice more.
But if 1 hour of DV is 12G and you edit annd make yet another  
rendered movie and then encode a DVD , another layer of rendering and  
iDVD is still
hannging on to your finished movie ( I render that way) then you are  
keeping 2g as opposed to about 16.
But only for finished product to be burned to DVD.
hich isn't to say you couldn't archive footage as mpeg2 but that  
isn't what this is for.
It does cut down on the iDVD project overhead.
