I'd agree that keeping the uncompressed source material is a good idea
and this is probably still OK for video. Though some cameras seem to be
coming out with record to DVD (MPEG2 - royalties via license to
manufacturers) rather than
raw DV to tape.

Can you take an uncompressed digital photograph?

The Film and Sound Archive in Canberra was looking into the archiving of
video footage - mainly to preserve the images they already have on media
that is deteriorating(spelling?).  This was proably about 10years
ago...anyone know where they are at?

On video compression formats, I am playing with MPEG4 (royalty issue
cloudy) and Theora (open source and format).

and giving a talk on this next Thursday to the ACS NSW FOSS SIG free and 
all welcome but you probably should register

It would be good to debate the issue of video formats.
