I’m not sure if this will help anyone else, but I discovered that I had brought my pup packs to grinding halt/total freezing by unchecking the “force full screen exclusive” box in the VPX global video settings. After I went back to forcing full screen, my videos ran perfectly.
A big thanks to the entire team on an amazing job! This thing plays beautifully, and I really appreciate the effort made to make installation and configuration a breeze. You knocked it out of the park on your first effort!
