need help in burning DL DVD

[5ColorRainbow]

hello! this is my first time trying to burn a DL DVD and i'm having a problem

i use a blank Verbatim DVD-R DL 8x (8.5Gb) and the image file is about 7Gb. but it keeps saying that there's not enough space on my dvd no matter what burning softwares i tried (Nero, Ashampoo, ImgBurn)

here is what it said

what should i do abt it?

thanks in advance!

That disc probably was damaged in a previous attempt. Try a new disc from the spindle.

 

That 3382 MB is not a correct size even for a SL disc.
