I have an ISO that when mounted is 4484 MB but my media only allows for 4483MB. Is there any way around this? I have a Lite-on 812S and am using Nero 22.214.171.124.
If it was a CD, I'd suggest overburning, unfortunately though, DVD drives don't currently support it.
Try some different media perhaps?
OrMount the ISO, and run DVD2one to recompress it
Then burn the files
