While I know there are proponents of DVD as archival media here, I think it prudent to caution that despite that last posting there are well documented cases of DVD rot occurring in a very short time (1-2 years) after burning.
Remember, DVDs we buy from the store are pressed and will last a LONG time, but DVD-r etc is a burn process and is not the same at all.
Don't put too much faith in them. I don't have enough experience to speak of reliability of brands, and don't know whether the rot happens with higher end disks or not, but be careful with blanket statements like "dvd will last longer."
