A second DVD-R won't solve the problem because optical disks degrade 
over time and the second one will degrade just as fast as the first. 
What you need to do is to check the disks periodically (once a year is a 
good time frame).
I myself would add a textfile with md5sums for all files to the DVD so 
you don't have to check them visually.
