Oh wait, you say you are selecting Mastering PanX 10.2. Those are paid videos, so you’ll see 0 selected if you haven’t paid for them. (You can see in my screenshot above that I have 78 videos, because I have access to both the Mastering PanX 10.2 and Deploying Shared Databases courses. So 57+12+9 is 78 total videos.)
You can purchase from right inside Panorama, to learn how to purchase see Purchasing Additional Videos on this page:
You can also see a detailed list of the curriculum of the course.
I wanted to watch that last training video in May 2022 and when I click on it on the left PanX Panel, I see the first screen, but when I push play, I hear the audio, and their play time cursor moves along the bottom, but the video display area is all black.
I logged into Vimeo and see all the paid for videos in my account and they play fine (Opera Web Browser) those play okay from there. But playing the free videos by clicking on them in PanX gives a black screen, WITH audio, when I push play
