How long will our dvd's last?

I am considering putting my vast video collection on dvd to free up much needed space.

I have read many questions about unknown dvd longevity though.

Fortunately the climate is dry in Colorado, I have that going for me.

Yes I know quality dvd’s will likely last longer but we all know that cheaper dvd’s sell well and frequently work just fine for recreational stuff.

How long do DVDs last?

Pressed discs (the kind that movies come on) should last longer than you will,
anywhere from 50 to 300 years.

Expected longevity of dye-based DVD-R and DVD+R discs is anywhere from 20 to 250 years,
about as long as CD-R discs.
Some dye formulations (such as phthalocyanine and azo) are more stable and last longer,
100 years or more compared to 20 or 30 years for less stable dyes.

The phase-change erasable formats (DVD-RAM, DVD-RW, and DVD+RW)
have an expected lifetime of 25 to 100 years.

In all cases, longevity can be reduced by poor quality.
Poor quality pressed DVDs may deteriorate within a few years, and cheap recordable DVDs may cause errors when recording or may become unreadable after a while.
