Carl.Fredricksen Thank you for reaching out and providing detailed information about the issues you’re facing with Passkey. Here are a couple of suggestions to help resolve your problems:
Please try running Passkey as an administrator. Sometimes, running the program with elevated permissions can resolve drive detection and processing issues.
Regarding the playback problems and the copyright protection error messages: please check if Passkey is successfully recognizing the Blu-ray discs by going to Passkey’s Settings > Info and looking for the disc information of those problematic movies. If Passkey has indeed loaded the movies correctly, please provide us with the latest Passkey log files. This will help us investigate the issue further and assist you better.
Let us know the results after trying these steps!
