When you put the disc in your computer and browse the files, do you see a BDMV file on the root of the disc?
Yes, and a certificate folder. I finally managed to get it to play on my panasonic by updating it. Problem now is I don’t know if my panasonic can play dual layer discs, because up to the 1:05:32 mark, it is on the first layer, but after that, it acts like it is trying to get the second layer but then just goes back to the main menu.
