(((After thinking it over a bit, I think that you are going to be more flexible
in delivering your wishes if you have a small video camera on your computer
that you can use any time to change/ edit your last wishes. They are
extremely cheap now ($20-50) and are readily available at any
computer/electronics store. They record in mpeg format.))))


Mpeg is one of several formats you should record in. You never know , Mpeg could
be 

phased out for a new version in 20 or years and could be compleatly incompatible

for the future. Multiple formats and (int this case codecs) ensure maximum 
compatability 
for the future. Allthough I would hope that people would update every 5 years 

((((Also, because, CDs and video tapes may deteriorate over the years (probably
10-50 years) I'd probably download it to a web server where you can maintain
it virtually for free))))


OR untill the raid array fails, that hard drive corrupts your data  Or the Site 
dissapears 

from the face of the earth. Never trust anyone but yourself when it comes to 
what will be the most 
important message of your .. death/ life 


CD-Rs that use Phthalocyanine as their data storage medium has a lifespan of 
about 100 years 

under normal storage conditions. Store the CD-R in an inert enviorment. In 
speaking with an engineer

at Kodak. He says that the data could last as long as 200 + years. Pretty solid 
I think. Since we may 
only need it for 60+ years (without annual updates) for people signed up now 


However you do make an interesting point about having a webserver. And one I 
would impliment 

if in a position to. Have each Cryonics company maintain a cryonics server that 
can download your message from anywhere in the world. If the CD is not handy, 
Then they could get it or stream live video 
to any machine they need to. 

(((for a long time. Your mpeg format is probably going to be the same format
that will be used for video in decades and if not, there will be conversions
from older version available. You'll be able to play it in Windows Media
Player or RealPlayer or any other comparable player using the same
technology.)))))


ER, Don't belive that for a second. I have several pieces of video I could send 
you 

that were encoded in a format from the Windows 3.11 days that will not play on 
my 
Windows XP machine.  the only way to ensure playback is to "shotgun" as many 
formats you can and hope one plays.  

(((((If you look at the state of mp3 technology today, you can play mpeg files
from 3-5 years ago easily, the quality will not be good, but it does it))))


Ahhh, 3- 5 years really is no test of time. Lets see if your MP3s play in 10 - 
15. years 

with the updates of digital codecs comming fast and furious, Don't count on it.
