DVDs are Obsolete

BTW I ripped my DVDs and now play them from the nas. Same for CDs. Vinyls are still played the old way.

Makes a well cared for vinyl record seem pretty long lasting really.

Although I suspect any reasonable media , even digital tape, chosen carefully and stored correctly to be used as a master copy rather than played continuosly will be fine for our lifetime.

Disc rot is more subtle than you are suggesting: after only a few years, your DVD will develop one bad sector and the movie will stop playing midway through; in a data folder with hundreds of files, one file will mysteriously develop a bad check sum and become unreadable; an external hard drive will work properly for a while and then suddenly start making rattling noises and become inaccessible. I know this because I have experienced all of these types of data loss from the obsolete technologies that you support.

If you want to make the wrong choice to archive your data, then go ahead. But please remember that I did try to warn you as politely as I can.

At my advanced age, archiving music and/or movies, is not important to me.

Am I really that lucky and unusual that this has never happened to me in 25+ years? Or to anyone else I know?

@DarkArts,

Here are 8500 examples:

Also note that the dye in recordable CD-R/DVD-R discs (used for astro data backup) decays faster than the dye in CD-ROM/DVD-ROM and commercial DVD's.

I believe the original DVD+/-R had a purple dye which was organic and would degrade quicker if exposed to sunlight. So that was if you were making your own copies. The commercial DVD data recording was a different process so the ones you buy last longer. I read about 10 years ago that some bank in the US had stored information on discs that became corrupted over time. I have DVDs that are over 15 years old in spindles with the purple die. The double sided type. I still play them. No issues so I don't know what timescale we're talking about before losing data. What I know is that my dvd and bluray player had to be replaced once but the discs are still fine.

Do you pause the video or just enjoy the show? I sometimes try but only rarely succeed.

I sometimes pause the video and sometimes get the right answer.

Hasn't happened to me yet either.
