audio/video does not sync when watching videos

I downloaded videos, mostly from JTAC collections and the audio & video does not sync. I am using Act video player.

Have you tried restarting your phone? You're the first to experience this with my movies and honestly I am shocked. I check all of my movies before posting them, specifically to make sure this does not happen. Which movies are doing this to you?
