Pete, the box set contains 9 Blu Ray movies. Two of them are not remastered and they work fine. The other 7 movies have been remastered of new and will not work. After starting the .iso file (with PowerDVD) the screen will be black. No picture en no sound. With the Leawo Blu Ray player also no menu but the disc start with one of the documentaries. Can you help me to solve this problem (I know I ask a lot with seven movies but there is no hurry). Thank you in advance for your help.
