[Cialug] rip an ISO

[Renegade Muskrat]

Awhile back i downloaded a Debian DVD and burned it. Now i'd like to 
make another copy. However, i've since deleted the original ISO. When i 
use dd to rip the burned DVD to an ISO, the MD5 sum is different from 
the original ISO that i downloaded. I don't believe the disc is 
corrupt, just the ISO that is ripped is different from the one that i 
downloaded. I've noticed this in the past with CDs as well.

Is there a way to rip a previously burned CD or DVD such that the ISO 
is identical to the ISO that was used to burn the disc originally?
