Wow, finished all the steps. Created an iso file, imported it into Express Burn, and after 6 and 1/2 hours had to abort. Threw out the DVD disc. After I stopped the program it said it was only 10% done. Super frustrated. Mac OS High Sierra. Plenty of memory back up and the single layer blank disc still had about 30 percent unused from the calculation. My video is only 1hr 27min.s and supposedly I took away all the "hard work" by creating the iso file. Scratching my head on this. Everything to this point was fine but, please help before I decide to uninstall and go elsewhere.
