Generally, Passkey will begin to examine the disc and request the resources it needs from the decryption server. In the case where the resources don't exist or don't match the disc you have loaded, it will attempt to analyze the disc using BluPath, which can be slow and require 10-20 minutes or sometimes longer. It will show you this if you tell it to "show baloontip" in Passkey Settings. For the present, I suggest you attach the Passkey log generated by this title after a lengthy scan, like the one you reported so the developers can evaluate it.

I enabled the "Show Balloon Tooltip" as you mentioned and it was actually popping up a new notification complete with ding tone every couple of seconds so I had to turn it off again.
These are never really new discs so the resources should be available, especially if they work sometimes. The one I have right now is a 2011 release.
I'll attach one log right now though it may not be useful. I put the disc in and let passkey run for about 5 minutes, though for some reason the "time elapsed" was reported as like 38000 seconds or something absurd. Then I noticed there was an upgrade available so I upgraded Passkey and the new version finished with the disc in like 10-15 seconds. Next time a disc goes on forever I'll let it run 20 minutes then put in a new log. Unless I'm unlucky enough to report an issue right before 9.3.8.6 fixes it, that shouldn't take more than a few hours.
