JDC, I downloaded potplayer from your links provided and it was the same file that I already had downloaded from the other site. I received the same windows protected your pc popup stating Microsoft defender smartscreen prevented an unregonized app from running from it again. I was able to download VLC and install from the link you provided without any errors. I played a few video files that I have and the audio played fine in all of them. Any ideas why it doesn't it allow me to install potplayer without receiving that popup message?
