Does anybody have an idea of the expected shelf life of a home burned DVD?
How does it compare to video tape?
How does it compare to commercially made DVDs?
With analog video tape the quality goes away - with digital (either it's there or it aint), it seems possible to one day load up a DVD to play, and it just not work at all.
What would be the best long term video storage solution?

The dvd demystified faq says:
Pressed discs (the kind that movies come on) last longer than you will, anywhere from 50 to 300 years.
DVD-R and DVD+R discs are expected to last anywhere from 40 to 250 years, about as long as CD-R discs.
The erasable formats (DVD-RAM, DVD-RW, and DVD+RW) are expected to last from 25 to 100 years.
I think VHS can last from 10 to 20 years without any real degradation. (It depends on where you store them.)
Dvd-R is the way to go. -
Thanks for the response... I actually did find this info after I started the thread, and I was coming back to post the answer to my own question...
Thanks again

The thing with CD-R/CD-RW or DVD-R/DVD+R/ect is that once it is authored to digital media; you can easily dup or copy to new media (whether it be a newer disc if you are concerned that the media may fail or to a future format) without any generation loss... unlike analog media such as videotape. You can also keep multiple copies of non-replaceable data (like your family's home videos of the kids) as backups or send copies to other family members.
Digital media is definately the way to go for archiving.
