I am using PE19 on a Windows computer. I have created a 1hr long video and cannot export it. I've tried burning it to a DVD which did not work so I've tried creating an ISO file which it says it does but the folder is empty. I am saving the ISO file to an empty folder on my C drive. I have also disabled the hardware acceleration and changed the main menu in attempts to export an ISO file but neither of those changes have worked. Any other ideas to try to get the movie exported and onto a DVD would be appreciated.
