Another issue some users have is when the program freezes while playing Blu-ray media. PowerDVD keeps playing the same frames over and over in an endless loop. It often happens when the video is reaching the chapter mark.
This seems to most often occur if you have any type of 4xxx card. You can update the card but the new card may not be compatible with your system.
A better solution may be to update your video driver, especially if you have Catalyst 9.3. Update to Catalyst 9.4. Your Blu-ray media may still look slightly corrupted, but it won’t freeze. You can watch the whole film, but the images near the chapter marks won’t look so great.
