I had no problem playing it through VLC.. Just can't seem to cast it. Works through the player on Chrome, but then there's no sound.

Trying to watch one movie, but it only plays it for four seconds, then it just closes. Played another movie and it worked fine, but this one just will not work! I don't know if it's too big, or what it is... It's a MKV that's just under 3gb. The same thing happened with this movie on Plex, so I thought I'd try it on here. Any ideas?
