If you’ve ever wondered why PowerDVD ultra 8/9 gives you an UNSUPPORTED FORMAT message when you try to mount some Blu-ray Disc images you’ve made after downloading a full Blu-ray , it’s because of some incorrect options have been selected when the Blu-ray was ripped to HDD with ANYDVD HD.
It should be - Enable Blu-ray Support > Remove BD+ protection > Prohibited User Operations > Disable BD-Live > Remove Blu-ray region code – For PowerDVD ultra to playback the Blu-ray Folder made in to a ISO.

Here’s what the folder structure should look like, but don’t worry if it’s not, because all you have to do is create any missing folders yourself to your downloaded Blu-ray and it doesn’t matter that they are empty as long as they are present before you make your Blu-ray disc image with ImgBurn.
