The Library of Congress have been backing up CDs for years but last I checked they were selective about which ones and probably the general public does more good for them with piracy. DVDs for the most part, if we're talking about movies, is not a format worth preserving unless the original movie reels/data no longer exist. The video resolution is too small and interleaving is garbage.

The source link is mostly about CDs in general, and also used a quote from a game collector about his game CDs. However, this can extrapolated to other forms of optical media. You're right- movies on DVD aren't really worth saving except as a footnote, and in the case you mentioned. However DVD media has been used on gaming systems as well such as Xbox, and of course newer systems use bluray. There's probably no immediate danger on bluray media, and even DVD games are not all that old- yet. But just as laserdiscs and now CDs are showing this problem, they likely will as well.

I've had a few music CD-Rs, both ones I've made, and ones I've bought, decompose into static. Proper produced CDs still seem to be fine. It may depend on how they are stored, to a degree.

Out of my 3500 or so disks I have I would say ~10 are unreadable. One of them was pretty cool it has rust spots. Most of them are just the plastic coming apart. Have not tried any CDRs from years ago to still see if those work. Those could be iffy. Most were temporary transport anyway.

> but how many have expanded this thinking to CDs and DVDs?
Cheap CD-R's are the most susceptible & apart from some early CD's, pressed media holds up pretty well. Even scratched media is pretty good.
Getting accurate reads from any audio CD is tricky though because the format and the drives weren't designed to allow it.
