F12-i386-DVD iso won't burn properly

[Temlakos]

I have downloaded this ISO twice, and verified it each time. I have made 
no less than three "coasters" while trying to create a DVD from it. Then 
I moved the ISO to another machine, and another program--which then 
proceeded to tell me that the ISO looked like a CD, not a DVD.

What's going on? Has nobody noticed that the DVD ISO is no good, and 
that the six-CD install set, or one of the two live CDs, are the only 
options?
