Error: Video suddenly stuck and audio continue

I have a problem with the current Infuse Apple-TV-App. When I stream a movie from my Synology NAS with SMB sometimes randomly the video stops on the current frame and the audio continue normally. The only way to fix this is move some seconds back with the remote control and play again.
After that the movie runs normally through.

I looked through the forum to find a thread with the same issue, but no luck. Is this problem known?

Thanks in advance!
