Ok got it exported to desktop.
Now the ImgBurn for PC app is really confusing and doesnt work.
Is there any other easy app to direct burn this thing to a Bluray now which can directly play on a BR-player ?
ImgBurn is powerful, and can be complex.
But the essential functions as there when you know where to look:
Click on Mode, then Ez-Mode Picker. If you build to an .iso, select Write. (If you built to folder, you'll use Build.)
In the "Source" area, click on the "Browse for a File." Pick your iso.
