Hi All: please keep in mind that an "archival grade DVD's which are 
projected to last 100 years" is a bit of manufacturer 
nonsense.  Although it may very well last that long, I strongly doubt 
that the equipment will be around to playback a DVD; even if you have 
a museum of equipment,one would have to make sure all the components 
are in working order and have parts available if something breaks/fails.

If we can get 10-20 years out of a DVD, we should be OK; we'll just 
have to be cognizant to migrate to the next storage media in a timely 
fashion.  I find it disconcerting that there is already anecdotal 
evidence that a recordable DVD will only last 2-5 years, but that's 
what mass production and poor quality control has brought to the CD 
and cassette markets also.

The problem is not new and there have never been simple answers for 
moving images and sound; unlike paper based records (at least those 
not created on self-destructing paper) we have always (or at least 
for the past 100+ years of existence of the technology) been running 
up against a time-bomb deadline with moving images and 
sound.  Hopefully, by transferring to a digital format, we will have 
a means to more readily and efficiently continue to migrate those 
moving images and sound of enduring quality.

Respectfully, Dan Noonan
