Blu-ray disc I created used to play on old Samsung player. Won't play on new Sony, Samsung, or Panasonic players. Why not???? in ImgBurn Support Posted September 8 I never did BD video discs so I am not familiar with this but as you mentioned ProShow Producer I thought I chime in... I don't know what output you've got from ProShow Producer back in 2014 but I just did it to try out. I opened the last compilation made with the program and selected Blu-ray to publish. It complained it didn't find the CD drive. I was expecting to complain for a BD drive as I don't have one but it just asked for CD drive. Anyway just got over it an created an ISO file. Mounted the ISO in Virtual Clone Drive to see what's in it. It has two folders BDMV and CERTIFICATE. BDMV has a bunch of other folders in it and other folders and files under the branch. CERTIFICATE is empty. Started VLC and go to Media > Load a disc... select Blu-ray hit Play. VLC showed an error screen about not having Java installed for playing back the menu. Got rid of the error and the show played fine. My assumption is that the ISO it created is fine and respects the BD standard and if it would be put on a BD media it should play in standalone player. Now, is the disc from the 2014 produced the same as I explained? It has the correct BDMV folder and CERTIFICATE? If its something else, you can't expect the standalone player to run it as a BD disc.
