If that is the case, then the other two things I would do is

1 - Do a md5sum check on your downloaded iso and make sure it matches.
2 - Make sure my burning software knows that you are trying to burn a 
DVD and not a CD.

If you've checked both of those, then it is beyond my knowledge of what 
to do.
