Command Line Info Message Suppression

[jeckels]

I have been using ImgBurn to burn a daily backup of files for years now without issue. It is run automatically from a batch file that executes in command line mode. We burn to dual layer BluRay discs and recently due to some file purges the backup has gotten small enough on certain days it will fit on a single layer BluRay. We always want to burn to the dual layer because we want the process completely automated and we never know for sure if a single layer will be big enough. The problem is if the data will fit on a single layer disc, an info box pops up to inform you and thus stops the automatic nature of the burn until someone answers the question. I did not find it, but is there a command line option that will suppress that warning/info message?

Turn off (uncheck) the following...

Tools -> Settings -> General -> Page 1 -> Display Warnings -> Underburning
