Time Capsule - Media Type - Last for 20 Years


I need to submit something for my Neices 1st birthday, as a time capsule she will likely open in 20 years. I want to include some video, music, and pictures. So that brings up two main questions for me.
1. What files types will stand the test of time? Although I can always include some codecs, etc, whatever I can find.
2. Most importanly, what Media Type should I use? I am thinking maybe DVD would be the best, and put everything in the format of a slideshow with DVD Maker. Currently I can still buy a VHS, which is 30 year old tech, so i assume in 20 years one could find, at least at a collectible store, a dvd player.

What you are thoughts? reasoning?

I realized I could have been more helpful.  Make sure to put it in a jewel case, and store it on its side (i.e. not face down on the data).

Here is a link for archivists and librarians and what they do to preserve data.


Here is a link so you have an idea of what the "gold label DVD-Rs" are (stay away from DVD-RW):


There is also some talk of cd/dvd rot, or bacteria that eat the aluminum in cd/dvd's, but is generally not found in a cd/dvd that was burned, maybe due to the process of burning the cd/dvd instead of stamping it.

Gold label DVD's have a lab-rated life-span of 100 years, if handled properly. MAM-A silver label CDs and DVD's can start to degrade after 20-30 years.  Stay away from VHS or anything magnetic.

mp3 and ogg and wav file formats for sound

jpeg for graphics

avi and mpeg for video.

Also try to use raw data when possible.  .tif for images, .wav for music, and .avi or a .mpg for video are the least compressed formats and likely to be easy to read by future hardware.  You might include a cd copy of Windows XP for some sort of emulation, but will likely be freeware like DOS 5.0 is today.  Those formats come readily viewable from a standard windows install and have already been around for 20 years.  (with the exception of upgrades to the containers .avi and .mpg)
