Well....now it's more interesting. I don't know if either the codec or the CORS changes affected the scenario. In a random sampling, I found several titles that *will* play; #288 (300), #193(Catch Me if you can), and #194 (Blackfish). 15 other random titles will not start. Including, but not limited to Tomb Raider, 12 Angry men, and 2Guns. There must be a pattern now but I can't see it. I don't think I have a way to interrogate the properties of each to try and compare them.
