I am in and only use N. American region Blu-rays, mostly burning my own videos. I have not made region changes, but now I suddenly can't play back a Blu-ray I just burned. Blu-ray disc plays perfectly on a separate player.
PowerDVD settings indicate I have 0 region changes left and it has defaulted to set computer country, which is USA. But it won't play a Blu-ray.
I also have a portable Blu-ray drive USB attached, neither drive will play back, making me think it is HP or Windows 8.1 rather than Cyberlink issue, but not sure where block is occurring. Both drives fine playing DVDs, only the Blu-ray copy protection ignores Blu-rays.
