I bought a pioneer external Blu Ray Burner. I am trying to burn my .ISO files of certain Bruce Shows but I am really struggling. Yes, I am trying to read up on it on the internet but I'm struggling. I bought the App Toast which is by Roxio to burn the Blu Rays but now I apparently need to download Toast Titanium to actually convert the files. That is $100.00. Can anyone point me in the right direction of a cheaper alternative or let me know the easiest way to burn an ISO file. I've tried Disk Utility but that has not worked for me. Any help would be greatly appreciated.
