What Verbatum's are you using? I'm not aware of any Verbatum DL+R that are 4X....the ones I use are a max of 2.4X....I think you found your problem.

Whenever I've burned one of these in imgburn, it was only at 4x with no options to change it.

This is what imgburn tells me about one of my blank Verbatim DVD+r DL's.

They have a lilac-colored label.
