I was using clips from twitch but it will keep saying load error. My other files work fine but just not these files.
More information on the video file would be helpful. Please list a MediaInfo tree report on it. How to use that here.
Chances are the problem files will need to be transcoded to something more standard. If you don't already have it, get a copy of Handbrake. Try transcoding the video and see if that helps. How to use Handbrake here.
