Unfortunately (?) I can't find any configuration options for this "Exclusion List" in AV. With Program Files\ImgBurn\ImgBurn.exe added to this list, I'm not able to test the difference.
ImgBurn.exe v. 1.3.0.0 did not produce this kind of behavior with Kaspersky AV, so I agree it should be OK.
EDIT: Oh, stupid me, I only have to install ImgBurn to another directory... Back in a minute.
